Everyone else will care about your mistakes.
They’ll criticise you for them.
They’ll talk about them to others.
They’ll refer back to them whenever it benefits their narrative.
The biggest mistake you can make though is to care about your mistakes.
As soon as you start caring about the mistakes you have made, you have lost focus and forward momentum.
Mistakes are always going to happen. Acknowledge them and learn the lessons from them. Then move on.
