It’ll just complicate your life and make you unhappy.
Life will pass you by if you let it, make sure you have some fun experiences along the way (concerts, travel, time with friends).
As you get older your friends will move away or will grow apart from you. Make sure you work to keep your good friends around, take the initiative, good friends are worth their weight in gold.
There’s no such thing as bad food, don’t demonize it for yourselves. If you demonize food it gives that food power, when it’s just food. You’re allowed to eat whatever you want.
