Productivity tips

What is it all about

First of all, don't take me for some cheap productivity guru. I am not one and I am not claiming to be one. I only plan to provide some tips and tricks for other students who seek to maximize their time efficiency.
For reference, at this very moment (2025.10.23.) I work 4 jobs: senior infrastructure engineer, 3D web designer + backend developer, private teaching and teaching at BME University. I also am part of the BME Suborbitals rocketry racing team and a week ago I participated on the behalf of them on the Techtogether+ competition with my other high skilled teammates. I also do some other cybersecurity certificates while studying in my university and do some research in the fields of mathematics, so I am pretty sure I can help atleast some people with my tricks and tips.

Sleep

Sleeping is non-negotiable for achieving a high brain functioning. I would say, ALWAYS sleep at least 8 hours, because if you don't, not even energy drinks will save you. It will allow you to focus for up to 4 hours.

Time management

This is the second important point. Don't do stuff for the sake of "necessity". At university if you feel like you need to skip a class to learn something instead, do it. You can only focus 4 hours at maximum. (More if you found the flow.) Also, don't fragment your time, if you have the opportunity. Always batch do subjects. Like wait until you have 4 hours of calculus then study that for 4 hours. And please remember to do excercises if you do a lot of studying. Study for 45 minutes and the excercise for 15 minutes. If you need to hear a recording, hear it while you relax, while you play a simple game. You can also study while commuting. This was my short tips and tricks. I hope it helped something.
