You can be mistaken about your high self-esteem
Sometimes we can think that we are the best, the most valuable, undefeated.
Maybe some coach assessed us that way too.
Maybe this coach even told us that.
That we don't have to do anything anymore.
That we can be calm about ourselves.
A good coach has this thing about him that you never know what he's planning. He probably doesn't even know himself :))
He'll throw something out there casually, leave something unsaid. And you get yourself into such shit that you'll have to work hard to get out of it.
And he calmly trains others.
Who you don't even know when they caught up with you, overtook you and only the smell of them remains :))
Because a good coach sees everything.
And appreciates hard work like no one else in the world.
