I was like that when I was young. Now all my plans involve me forcing myself to do 1 or 2 productive things a day besides the stuff I have to do, and then just calling it a day and pushing aside the rest of the stuff I probably should do till tomorrow. Or more realistically, the next weekend or holiday.
I don't lie to myself anymore, I just admit that if it's not 100% vital, it won't get done quick, if at all.
Mid 20s here, this is what I've ended up at too. I prioritize how much each thing needs to be done and then force myself through 1-2, sometimes even 3 as early in the morning as I can. Otherwise it doesn’t get done
