They way I think about it is you can work a dead end job for 80 hours per week making $8 an hour to make enough to survive and not have any free time to socialize, go to the gym or be with family. Or study for and try to get a decent job you like that pays half decent so you don't have to become a human eraser and wear yourself down doing the work of others. Having many skills to fall back on is great but trying to learn everything losing focus and never finishing anything isn't much help.
Or realize you need to focus and find a career that you like and is wanted by employers. I recall years ago they mentioned "The fear" and it is a great example of suddenly realizing shit I better start getting good at this life thing, now!
Time is shorter than you think your health can suddenly rapidly fail, saving for retirement is a constant worry. Time is so short it's as if nothing you do can be done soon enough. Realizing that early in life is fantastic. A big part of life I think is having mentors who are examples to follow it's good to have a person who you can think "What would Bob do?" as an internal guide.
It's easy to say all that but hard to do, I haven't mastered that yet.
