I found this YouTube video of Tony Hawk awhile back that was shot as he was trying out a new trick that many of would fine impossible to do.
My favourite part in all of it, was the anxiety he felt in trying to do something new, the push to get there, the lumps and bruises he was taking to get there.
Your lumps and bruises might not always be on display as you work to achieve a new goal, but they are there.
And even the best get nervous when trying something that has never been done before.
But when it works… well just watch.
