I wasn't quite 40 when I started (for the 3rd time........alot of things went wrong in my life from the 1st time at 19!). I was alot older than 80% of the students; had alot of "life" experiences. But, it was well worth it!
I was very lucky when I went to school (graduated 10 years ago at age 37). I was a single mother, of Spanish decent, with very good grades! I received alot of financial aid and I worked almost full time (though my school HIGHLY recommended that we didn't work! How was I going to feed my kids!
After 19 years of schooling, either full time or part time, I ended up with only $5000 worth of loans. I was very lucky; some of the younger ones ended up with >$20,000 worth of loans.
I think being older helped me cope with the high stress of school! I don't think I would have done very well with school if I was younger (esp the way my life went......that is why it took me so long to finish!)
Go for it! YOU CAN DO IT!!! You will make a great nurse! Good Luck!
