No one.
Perfect SAT scores. Great grades. Most creative in class. Most encouraged in class. Rejected by every college but one.
After graduating college, rejected by every prospective employer except Denny's.
Taught myself to program and gave it away until someone hired me.
Ten time employee who quit every company because someone got promoted over me even though I did 3X the work.
Beat the pavement but couldn't find customers until I wrote the software first, then they purchased.
When friends & family saw how much money I made, they all wanted in on it until they saw the sacrifice I expected from them, then every one backed out.
Rejected by Alphalab because "no one would buy" what I had already sold many times. Rejected by Ycombinator because they didn't think anyone would buy what I had already sold many times. Rejected by Incubate Miami because they wanted to see a business with a product and customers first. (Then why would I need you guys? I thought the whole point of these programs was to find otherwise unavailable opportunities by giving prospective founders a break from their other responsibilities to be able to focus on just building.)
Rejected by prospective cofounders who didn't want to make the same sacrifices I have made.
After being underestimated by the cool kids, teachers, girls, family members, employers, and strangers for being an ugly skinny nerd my whole life, I thought it would be different in the tech world, but it's not. It's still a beauty contest based primarily of superficial subjective perceptions. People are still often too lazy or unable to dig below the surface to find the reality.
Please don't misunderstand. I'm not bitter. I'm glad...
I wouldn't be half the builder I am now if someone would have given me a break along the way.
So I just keep on building and loving it.
