well i was in your shoes. i worked for a very large company making about 60K a year repairing steam boilers and refrigeration units. but i was bored and wanted a change in careers. i had the itch to become a RN so i took night classes to apply to RN school and was accepted. i finished and graduated 2 weeks ago. i was hired before i even finished school at the local hospital making 10K more than my last career. so if i was you, go for it, i would target your RN not LVN of you can. the road will look long, the jurney will be difficult, and it might seem endless. but i you can do it and when it is over, you will be so thankfull that you did. i know i am. good luck!!
