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?
Fatigue is normal, but will get worse over time if you don't address it.
First, recognize that you might be putting too much on yourself.
If you studied / programmed 10 minutes a day, every day, you would achieve more than someone who studied 2 hard hours every weekend.
So consider whether you'd be fine doing a half an hour or less on some days if you don't have the energy.
Also as others have pointed out, memorizing everything isn't that useful, practicing is.
Build something fun!
