Keep Trying!

Well said, Nelson Mandela.

As a coach I often have the conversation about "Trying", and I always quote Yoda - "Do, or do not. There is not try."

However, I'm prepared to let Nelson off the hook on his language this time, as the wisdom of the quote is worth noting.

No one is perfect. 
No one. So you don't have to be, and since no one is perfect, what's stopping you?

Failure is part of success.
In NLP we say "There is no failure, only feedback."
Well, that's right. And still sometimes it feels like we have failed. You tried and it didn't work.
Big deal!
Do it again, or do it again differently. Keep doing (or trying if you must) until you can do it.
You didn't walk perfectly first time, you probably fell over more times than you can remember, but once you learned to walk that didn't matter.
You were really bad when you first started driving a car.
If you've ever learnt to play an instrument, you were terrible at the beginning.
Could you touch type the first time you saw a keyboard?
Could you stand up and ride a wave on a surfboard the first time?

Whatever it is you are trying to achieve, if you didn't succeed the first time, why is that a surprise to you? Keep doing until you can.

To your success,
