Do any of you guys ever feel like even though you're going down the best path, the grass is greener on the other side?

I feel like I've spent my early 20s understanding equations and relationships and while it's required for what I want to do, I look at other people in things like arts having the time of their lives.

t. mechanical engineer btw. For the most part I like what I'm doing, but I just feel like people in STEM generally have shittier early adult lives than people in arts. I get the whole delay of gratification thing, but I'll be so fucking old and gay by the time I actually get to where I want to go.
