It always seems impossible until it's done.

Don’t practice until you get it right, practice until you can’t get it wrong.

There is no talent here. There is hard work and obsession. You could be anyone if you put in the time.

Don’t hang your targets after you’re done shooting.

Nothing is impossible if you want it badly enough. Impossible = I'm possible.

Fall down seven times, stand up eight.

Your attitude is everything. Pick a good one.

The boxer is not afraid of being knocked down, he is afraid of not being able to get up again.

Success can never happen without the journey (struggle).

Start, struggle, fail, fix and learn. Repeat.
