meaning of life

I'm sure this sort of rant has been done many a time here, but anyway..

I worked really hard at high school. Studied really hard to get top grades to get into a top university. At university I worked round the clock, academic work & extracurriculars to get internships, to get a good graduate job.

Today on paper I'm pretty impressive on papers compared to peers - a 23 year old Associate making a nice 6 figures. I do like my job and am proud of my career, but on the other hand I'm permanently tired and don't get enough free time to do what I want (sleeping, chillaxing, the usual).
