… is a very good start.
“Do unto others as you would have them do unto you.“
But I suggest you take it one step further:
“Do unto yourself as you would have others do unto you.”
You wouldn’t want others to be critical of your every move. You wouldn’t want others to hold your past mistakes against you. You wouldn’t want others to always assume the worst of you. So why do you inflict this on yourself?
You’d probably prefer them to treat you fairly. To give you the benefit of the doubt. To forgive your shortcomings and encourage your efforts to be a better person.
Make the first move. Whilst you’re waiting for others to treat you right, get the ball rolling by treating yourself right. Give yourself the gift of always having someone in your corner.
