A little bit recently. I have been in school part time the last couple years, but just returned to school full time this semester and moved from Avon (by Vail for those who do not know) down to Denver. I am taking 17 credits of science classes this semester and should graduate with a degree in neuroscience this upcoming summer. After that, I have one more year of schooling to finish nursing school and then I have a little more freedom again.
Before this year, I made 60+K a year waiting tables in a fine dining restaurant. I traveled to foreign countries and took 4-6 week long vacations every six months. I have had a blast with it. My job allowed me income and time off to become a pretty decent mountaineer and do/learn some amazing things. Unfortunately, I grew to hate my job. Over time, no amount of fun in your free time makes up for working a job you hate. So now I find myself buried in school work (I do enjoy learning, but being taken away from mountains all the time is difficult).
For me atleast life is about balance, particularly in three things; time to do the things you love (be they work or play related), money to provide the lifestyle you want (mostly to climb the mountains you want), and a job/career that you enjoy. For me, critical care/emergency nursing (hopefully eventually flight nursing) fits the career needs of money, time off, and having a job that is stimulating and enjoyable.
I do find myself wondering though, quite often recently, what I am doing when I find myself cancelling plans with friends to go climb mountains in favor of locking myself in a room all weekend to study.
You have to keep your eye on the prize though. I was working a job I did not like, so now I am sacrificing some mountain time over the next two years to change the part of my life I was not happy with. For the first time in my life I am adjusting to the substandard weekend warrior lifestyle. It is quite a weird feeling.
