You shouldn't drop on the floor like a wet mop.
But I think you can never be omniscient and all powerful either.
Obama and Trump certainly learned that.
We are all limited, but we are all equally powerful.
It's base nature to think - what do I want.?
What do I think is best? But it's also weakness.
You'd get further by thinking what do we want? Want is actually best? It's hard... but it's worth it.
And don't give your power away to people who tell you their way is best. I guess that includes me here :)
Just please value them as equally as you value yourself.
You don't need ego in order to have self confidence.
