I don't want to become a workaholic..., but other than that I'm organised and busy(timeboxing, fully implemented GTD methodology, passively time tracking, prioritising).

I just have trouble deciding how much time to time-box for a leisure as a 20-21 yo CS student... too little and I burn out if I don't plan it - I will either forget - again burnout issue, or procrastinate, as I can procrastinate even by watching documentaries too often or taking short trips too often...
