Why are you living?
When young minds come to me concerning having few hours and lot of work to be done, I just tell them to set their priority right. You cannot be a student of a higher institution and you spend 18 hours of your time playing video games. That is so not right.
Do first things first, there is time for everything. Read when it's time to read and play when it's time to play. Know what you want. If you don't get your priority straight, you may end up crashing and it will not be a nice scenario.
Do the more important stuff first before doing the less important stuff. Many people fail in life because they never got their priority straight.
