Its gets easier, even monotonous especially if you have higher education. Its ALWAYS way harder to start your career then it gets easy if you do well for yourself.
I didnt come from a good background, i failed hs. I used to slave away so hard. I went back to college, then uni. It took a while but now im making 120k per year solving complex legal cases.. i work about 6 hours a day, from home long story. Im still miserable. Golden handcuffs havent made it any better. Ive come to the conclusion that work just wont make me happy. I love to learn tho, and will go back to uni to learn computer programming soon I think. I have lots of hobbies like art and restoring old boats and other vehicles that have made me happy. Im not even 30 but i sound like an old man.
Idk i think some of us would be better off working for ourselves. But doing that from scratch is risky. Better off making a career and transitioning into it.
I dont really know what to tell you except that it gets easier. If your lazy and stupid though youre fucked. You can only be one of those things
