What's in it for you?
In every task you do, know that no one owes you anything.
The reviewer doesn't owe being nice to you. Your customer doesn't owe it to be nice to you.
Once you click 'Submit' or press 'Send', your work is not only 'yours'. It is open to the world.
So, let it be. Let go.
You'll be surprised by the results in the longer run.
