Depends what you want to win?

You won’t have happy kids and a good family life, if you don’t think it’s possible. Same as you won’t make a cool open-source library, if you aren’t optimistic (or naive) enough to go work on that.

And if you keep saying everything is impossible a huge drag extremely worthless and why even bother trying, you won’t get the fun projects at work.
