There are things, which we can't control or influence:

Everything that has already happened
Other people's opinion of us or reaction to us
What someone else does or thinks
The weather…….

So what can we do.
We always have acceptance.

Unfortunately, when we think of acceptance, it always seems a weak and passive thing to do. The reason is that we attach a story to acceptance, which is that we are taking on a burden without any choice.
But nothing could be further from the truth.
Acceptance, without a story, is facing up to and accepting reality. This is a powerful, strong and courageous attitude.
We have the power to make a choice and accept things just as they are.

The Serenity Prayer, gives us some very wise advice.

God, grant me the serenity to accept the things I cannot change,
courage to change the things I can,
and wisdom to know the difference.
