Watching for kids is very fun.

You will never see a kid who gave up tries to walk because there were hundreds of falls before.
But you can find that the kid continuously repeat any actions until they become automatic.
Like kid can spent a day learning an angry facial expression to try it the next day on playground with other kids.

Kids don't have a memory of failures but have highest motivation to reach their goal.
And this we can learn from them.

Of course, we are grown up. We don't have so much energy for continuous reiteration until something will work out suddenly.
We use experience to find more effective ways... And here is the trap - some people just find themselves unable to give required effort to achieve what they want.

And as always... Things are not so straight and depend on situation.
