Persistence is how you overcome resistance. An interviewer asked Elon what he thought about the challenges with launching an orbital rocket in the early days of SpaceX.
Interviewer: After that third rocket failure did you think about giving up?
Elon: Never. I don’t ever give up. I mean (if I was going to give up) I’d have to be dead or completely incapacitated.
Try, try harder, and try again.
And believe in yourself. You can only achieve great success when you keep trying and truly believe you can.
