Well you have to support your family and my current career does that for me. However I don't know where it is going, and I enjoy medicine which is why I went down this road. Money is important, but so is happiness. You need to find a happy medium. Don't wait until its to late to go to school, only to find out you wish you would have done it. Its the worst feeling.
Paramedics make pretty good, shoot for that. Over here they start out at $16/hr, still less per hour than I make now. But you work 120 hours every two weeks which is $2240, this is equivalent to $28/hr 80 hours every two weeks.
There are extra shifts to pick up to. Top pay over here is around $28/hr base, probably takes 10 years experience to make that though. Anyhow you won't make it as a basic but you can make a decent living as a paramedic in my opinion.
Also working 10 days a month is way better than 20.
Also if you plan to go to medic school, most require real college A&P I and II. Mine required A&P I, with A&P II required in the curriculum. Glad I made a "A" in it, if it would have made "D" then bye bye paramedic school.
