Studying feels much harder than work?

I find it much harder to stay focused and disciplined with school, as completing tasks requires a lot more effort.

In contrast, work feels much easier because I naturally get a strong psychological push—an instinctive "I need to do this" mentality. There's no resistance to getting things done, and I don’t have to force myself to remember details; the natural motivation helps me retain even the most specific information from weeks ago.

I don't understand how people get put in 8-6 including commute and study beyond 1 - 2 hours.
