I feel like I need to improve the way I manage my time. As TRP always says, the most valuable resource you have is your time. I've always known this, and always kept this infront of my eyes. However I keep finding myself wishing a day was 36hours long instead of 24, constantly. I'm still a student at university. I don't work besides uni, but some of my classmates do, and I can't even imagine how they do it. And they seem to have plenty of time to socialize besides going to classes & working. Yet I can barely find my time in between lifting, trying to have a social life, and trying to make time for my hobby.. (I mean in the free time I have left outside of studying). I often find myself surprised that the day is almost over while it felt so damn short, yet I feel like I'm constantly in a hurry, and don't even have a minute to let my mind unwind.

I need to somehow get a grip of time, manage it better, any advice?
