Serious question of the week

You know how eating a bucket of spicy KFC taste so damn good despite knowing you have a hemorrhoid protruding just barely out (not the case for me just for dramatic effect), your rectum telling you to crap but you're also constipated, you're barely defecating and taking a long time in the bathroom, and be in morning classes at the same time? 

Honestly that happened to me, but instead this is my way of trying to hook you about how to deal with urges to indulge yourself. Mainly quitting my gaming addiction after playing for more than a decade, but then I see my favorite games (e.g. on Roblox) release the sickest updates and I'm tempted to start playing it but worried about how it will affect me.

So long story short. I recently got into senior high and I made a promise to myself to take this shi serious since I dream big, but scrolling on the homepages on youtube is really testing my faith in my promise. I spend a quarter of my night thinking about it, how awesome It would be experiencing it. However I know that you better stay on top or life will kick you in the ass. Frankly I'm kinda proactive, but I hate work as much as you probably.

Ion wanna waste my senior high years but I wanna also try dem out....... Whats your way to either balance it with time management or cut it off completely
