I really love computer science, coding and mostly all the amazing things you can do with this knowledge, i feel i finally landed in my world.
I'm doing a Javascript course now and while it is really engaging to learn about how a language like that works and how to build with it, i'm getting quite tired and frustrated..
Now, i'd say i am quite meticulous when studying and i use some studying techniques to really integrate what i'm learning, but that means that 1h or even less lesson can take me all the time i have to study in a day to be understood, noted down and then repeated over the following days..
There are a lot of quite complicated concepts to understand and memorize, and, as i'm also working, sometimes it gets quite tiring.
I feel like there's this huge amount of never ending work and concepts before i can actually start do something cool with the knowledge i have, and i really want to start doing something cool.
I re-started to study after many years so i'd say it's also because of that if i'm not really used to it and i can't process much informations at the time.
How can you get better into gaining knowledge? how can you prevent getting fatigued?
I agree. When I learned programming over a decade ago, I didn't follow a course and I'm not sure courses were particularly widespread. Looking back, what I made was terrible quality but it got better with time. At first I'd even copy entire sections of code into place unsure of what it really does and eventually I would make it work. It sounds like OP is much further along than that. Just make something, it's the best part!
