How many times have you read or heard your ego is your worst enemy, that you block your own light, that your self is getting in your own way?
But how to do something about it?
There are a number of traditional solutions: practising gratitude is one.
Then there is pushing your own sense of tolerance. Note the things you just won't or can't tolerate. Then experiment for a while tolerating them.
These are shortcuts. If you don't use them, over time- maybe years- life will deal you an ego blow. It is of course, up to you how you react to it, but it'll come.
