NMLN, I think you should go for it! If you have a good idea, and a good buisness plan....well, don't limit or edit yourself....And pursue your passion. Passing on a chance to achieve what gives us meaning, could mean passing on our Purpose in This Life.
I had a small coffee shop about 13 yrs. ago in a small rural/suburban town. I worked 7 days a week...up @ 5am, open @ 7am, home @ 8pm. I was fortunate enough to operate in the black until, unfortunately, I had health problems, and knew it was necessary to liquidate, and take care of myself. However, I never reflect and feel regret or despair. Rather, I feel like the recipient of perfect gift...a perfect stepping-stone, that led me to the perfect place,....."now". zzzowl
