Sales or a Laundromat?

Hey guys, haven't posted in a while.. Long story short.. i'm 29.. a teacher and I want to make more money..

I also want to leave teaching..


My 2 options/ideas are:
1- taking this summer to get a sales job and if I do well, then quit teaching and do it full ti,e..
2- investing in a laundromat, and if it's successful keep buying them and that's my fastlane business..

any thoughts?
