Bravo to you for going back to school! And you are right. There are always 2nd acts - or maybe 3rd! My comment about it being “one shot” was meant to say “do what interests you in college” without so much “fear” about (or attempt to control) the future. Your first (and maybe only) college days should be your first attempt at in-depth learning and mastery of a subject while balancing the many demands of life. There are many transferable skills in the college experience particularly if you love what you are studying and become very involved. Learning is a life long pursuit.
Which reminds me I have to sign up for more of those darn “continuing education” classes…I have to admit I don’t love those…
