If it wasn't painfully difficult, you did it wrong.

Doing it right is hard. Doing it over is harder.

Yeah, what I did was wrong.

If you like an exercise, chances are you’re doing it wrong.

Take great care to avoid mistakes when the decision is hard to reverse.

But! If you make a mistake that is hard to reverse, there is no sense beating yourself up about it. Your responsibility is to make the best next choice given your current position. You must always make the most of the situation you are in.

Next play mentality.

If you're not having fun, you're doing something wrong.

If a thing is worth doing, it is worth doing badly.

Anything worth doing is worth doing badly.

The most difficult jobs look easy until you try to do them.

When it comes to changing your life, if you’re not scared, you’re doing something wrong.

Don't wish it were easier. Wish you were better.

I say again, impossible.
And I correct you again. Difficult. 'Difficult' and 'impossible' are cousins often mistaken for one another, with very little in common.

Here's a rule I find useful:

You should attempt things that are difficult enough to guarantee some early embarrassment, but important enough that long-term regret is unlikely.

Trying something difficult will usually make you look foolish or inexperienced. That’s fine. That's the cost of learning.

But if it's important to you, then you'll work through the early failures and — even if things ultimately change shape or don't work out — you'll never regret going for it.

It is hard to fail, but it is worse never to have tried to succeed.
