I kinda have to agree on that. I'm on exam periods and still can handle to go 3x/week to maintain

Sometimes it's not the exams themselves, but how your body responds to certain types of stress. Some people literally become fatigued and drained physically/emotionally while others don't. Cloudkicker can probably explain why or why not and I'm actually wrong, lol.

I know there's days where I feel ridiculously tired and don't want to do this or that, let a lone lift. That's why I usually drink preworkout because it becomes a process, once I start it I've got to finish said process, even if I have a terrible workout.

I also think some people have a easier/harder time talking themselves out of doing something. Like it's easier to put things off.

time management and self discipline

yup, but I bet there has to do with being raised as a child and being allowed to put off certain tasks, and other shit like that, that may make people more likely to follow thru or just stop easily

maybe to a slight degree
but u can change your habits and develop better ones

Yup I agree, or make them worse haha.

I just know for me, personally, if I allow myself some time to think about doing something when I'm feeling tired/lazy, I'll rationalize. "Oh I'll wake up early and hit the gym before work." Doesn't always happen haha. So for me when it's time to go, I just Nike that shit and just do it. The more you think/contemplate the more likely you are to allow yourself an out, an excuse.

lol'd let me guess business major?

science majors often require much more study time

i know a few business majors, and yeah they dont study much at all

i think it has more to do with the fact that some people have strong minds/psychological coping mechanisms where others wallow too easily

If your a big motherfucker theres really no reason to go to school, anytime you want something in life just flex on a hoe and its yours.
