Contrary to popular belief, not all learning leads to enlightenment and self-development. Oftentimes, lousy learning practices can lead to the contrary. Instead of acquiring in-depth and meaningful knowledge, you end up learning random and superficial pieces of information of questionable credibility.

In other words, stupid learning can turn out to be a waste of time, whereas smart learning will, unsurprisingly, make you smart. As such, it should be a priority for any self-respecting student or professional.

Unfortunately, most people learn by feel. Partly because of the undisciplined approach to knowledge acquisition and somewhat because smart learning has become a bit of a trite slogan in recent years. We all know we should do it, but hardly anyone knows what it is.

Let's tackle this topic step by step.

What is smart learning?

There are 5 key traits that characterize smart learning.

2. Choosing the right learning materials

There are 2 types of sources of information:

(1) Primary sources

Primary sources refer to previously established scientific facts (e.g., math, physics, and chemistry textbooks) or firsthand, fundamental research that is based upon observations or experiments (e.g., research articles in journals).

(2) Secondary sources

Secondary sources or secondhand sources refer to any learning resource which loosely relates to the primary resources and/or interprets them in a certain way (e.g., interviews, YT videos, etc.).

Roles of both sources of information

Both types of sources can be very useful in learning. The first one provides you with the certainty that the information you acquire is true.

Secondary sources, on the other hand, can help you make sense out of that information.

Sometimes hearing somebody's opinion on some matter can help you connect the dots and arrive at the right conclusion.

Always prioritize primary sources

As long as you focus on relentlessly acquiring knowledge from the primary sources, you can rest assured that your expertise will keep on growing and will be of the highest quality.

​You scarf down any crap which people dish out. And make no mistake. There are very few people who put in time and effort to really learn something.

Most simply regurgitate different anecdotes and old wives' tales to boost their ego.

Unless you prioritize learning from the primary sources, you will never be able to tell what's true and what's not.

Trust the facts, not the experts. Way too many people have their own agenda and have no problem with profiting from the naivety and ignorance of the others.

If you want to see for yourself how wide-spread that behavior is, go ahead and look up some popular language-learning websites. You will be lucky to find even one quotation on most of them.

As Dr. Johnson so wisely observed, truth is hard to assimilate in any mind when opposed by interest. Moreover, strong feelings about issues do not usually  emerge from deep understanding and knowledge.

3. Knowing what you can forget

It won't always be obvious to establish what's relevant and what's not. Sometimes only time will tell. There were times when I started memorizing random stuff only to realize after some time that I don't need to know it by heart. 

Definitely, one important criterion which can help you guide this decision process is choosing whether you want to master a certain discipline or be decent/good at it. 

Personally, I wouldn't decide to learn a lot of scripts or commands by heart if I was just programming for fun. However, if you want to learn a programming language to the "native" level of familiarity, you can't be too picky. In return, that will allow you to sketch out personal utility software, scripts, and hacks rapidly.

When memory researcher Jennifer McCabe posed a similar question to college students, she found an overwhelming preference for the second strategy, restudying, even though this approach is known to be inferior to the recall method in this situation.

Why did the students get it wrong? 

Most likely, they based their answers on their own experience. They knew that when they finished reading material over and over, they felt confident in their memory. The facts seemed clear and fresh. They popped into mind quickly and easily as the students reviewed them. This is not always so when recalling facts in a self-test—more effort is often required to bring the facts to mind, so they don’t seem as solid. From a student’s point of view, it can seem obvious which method—restudying—produces better learning. Robert Bjork refers to this as an “illusion of competence” after restudying.

Illusions of competence are seductive. They can easily mislead people into misjudging the strength of their memory, and they can encourage students to adopt study methods that undermine long-term retention. The best defense is to use proven memory techniques and to be leery of making predictions about future memory strength based on how solid the memory seems right now

5. Concentrating On What’s Evergreen!

One of the best ways of amassing impressive knowledge within a relatively short period is concentrating on what's evergreen. Even though it's not possible in every single case, I believe that this is something we all should strive for. Political leaders will change, programming languages will evolve, but physics, math, and even psychology will remain almost unchanged at their core.

Focusing on those subjects will allow you to build evergreen knowledge that can be applied almost everywhere regardless of circumstances. What's more, the more you learn, the easier it will be for you to expand your knowledge. Every discipline contains nuggets of wisdom that can be transplanted into other areas.

In other words, the more of such knowledge you gather, the quicker you will be able to learn!

Does it mean that you should try to master all the big disciplines? Of course not (unless you want to). Be picky and adjust your choices to your needs.

Whatever you do, remember this. Acquiring evergreen knowledge is an investment that will keep on giving and will never go to waste.

WHAT ARE EXAMPLES OF EVERGREEN KNOWLEDGE?

Summary — What is smart learning and how to apply it to become a better learner?

Smart learning is a fantastic learning philosophy. I am not only its big fan, but I also practice it every single day myself.

It can be seen as the best of the worlds, i.e., productivity and the science of memory.

At its core, smart learning involves 5 key elements which, if applied correctly, can help you to learn faster and become a better learner:
