We always do the best we can. All of us.
Someone may be doing better or worse than we are...
but that does not mean we should be dong better or they should be doing better.

We could do better, but right now this is the best we can do.

We make mistakes.
We say and do things that cause harm to ourselves and others.
We do not say and do not do things that can cause good for ourselves and others.

It is good to realize our mistakes and beat ourselves up for them.
But moderation is important.

Just beat yourself up for 5 minutes.
After 5 minutes figure out how to not make that mistake again.

If you cannot figure that out yourself, ask for help.

If you make the same mistake again, just repeat the above instructions.

Remember:
5 minutes is the time limit for beating ourselves up.
After that we just continue to do our best...

Because after all:
We are always doing the best we can
