Your boss is not thinking about you. Your peers are not thinking about you. You need to think about you.

“The key to happiness is to lower your expectations.”

This doesn’t mean you shouldn’t go after your goals. It means you should prepare for an imperfect path on the way. For example, when Roizen travels internationally, she assumes her checked baggage will be lost, that her flight will be late, that the rental car won’t be there waiting. “I assume everything that can go wrong will go wrong so when it actually happens, I’m not stressed,” she says. “I have a change of clothes in my carry-on; I schedule no meetings within two hours of landing; I expect the mess, and if it doesn’t happen, I’m pleasantly surprised. 95% of stress is self-inflicted.”

This is hard,” her daughter said. “But I like hard.” “I love that line,” says Roizen. “When you’ve been through a lot of hard things, you know that the best times are when you get through them.
Funding can make you do things that you never would if you didn’t feel like you had to.
You figure out what your product is only after selling it.
Traditionally, companies build a product they feel good about and then try to sell it. Firefly started selling before its product was fully baked, and it turned out to be one of the best decisions they made. “We did a lot of outbound sales, cold calls, cold emails, and it was so much better from a learning perspective than using something like AdWords to sell the product,” Shipper says. “So many people say that to test an idea you should just throw up a landing page and buy some AdWords and see who you attract. Unless you have a lot of experience with AdWords that’s a bad idea. There’s this gigantic learning curve to doing online marketing right, so most likely you’re just going to buy ads that no one ever clicks on, or you’ll get people coming to your page who immediately leave when they see nothing real, and then they’ll never get converted. You could have the wrong keywords, bad ad copy, who knows?”
You have to pair relentlessness with something else, and I think the best thing is being scrappy.
A useful, if somewhat simplistic, mathematical formula might be: a realistic view of the situation a strong view of one’s ability to control one’s destiny through one’s efforts = grounded hope.

You need to make a distinction between denial about the situation and overconfidence in your abilities.

The first one is very bad, but the second one can be surprisingly good. See the world accurately — but believe you are a rockstar.
