I've seen tons of founders quibble over a few percent, and none of them were successful. Successful founders get past those issues and execute."
Really? You only get 100% to give away. Every 1% you give away now dilutes what you give to attract future employees, investors, etc. OK, maybe the accelerator asking for 10% is better overall than the one asking for 5% for the same amount of funding - still, you want to be aware of that tradeoff, no? You don't want to be completely laissez-faire about it. It's like millionaires from traditional industries who'll split a restaurant bill to the penny - cultivating a mindset to be really, really careful with key resources.
"Successful founders get past those issues and execute." It might just be the wording, but this sounded weird on first reading. Like saying "only losers care about their own interest when entering a business deal - what are you, a loser?!?"
