-protohassassin has some secret formula for this shit. the kids in uni taking comp sci while clocking in 80 hrs past 2 weeks
I left tf2 running for an entire day by accident LOL
but it seriously just comes down to work ethic and time management skills, there used to be a point where I was like really addicted to tf2 and like I wanted to play all the time, now its just like, I've lost half the drive and energy I used to have when I was like 13 years old, now Im 18, I have priorities and until TF2 can start paying bills then it is absolutely not worth jeopardizing your education and future for (especially if you have brown parents).
Also here's my secret formula: If you are trying to play TF2 or trying to get into comp (since you mentioned lobbies), You need to finish all your hwrk/study/whatever, and then when you are actually freed, you will play better because subconsciously you know you have nothing due. I used to hold myself back because i did a half ass job at keeping my concentration on a scrim or w/e because I was thinking about my hwk or due projects, but its really up to you man, you have the energy because you are a player trying to climb through the ranks, you have that drive, but you need to prioritize the more important things in your life, that is until TF2 explodes :B1:
