"Thats what my dad's been saying i just didn't want to listen to him."
Listen to him - I quit school at 15 saved 27 grand by 19. BCPL at the same age and at 25 lost my medical.
I had nothing to fall back on. Absolutely nothing. I always though that it would never happen to me but it did.
Make sure you have a back up plan. It took me years to get back on my feet.
