Acceptance does not mean giving up. It means to stop fighting what has already happened.
You can't change the past. But you can change your attitude to what happened and how you will live with it in the future. And these changes start as soon as you stop arguing with reality and trying to make everything different.
Acceptance does not mean approval or agreement with what is happening. It's a quiet but conscious decision not to waste your life fighting something that can no longer be changed.
When you accept reality as it is, your hands are finally free. Now you can focus your energy not on fighting the past, but on creating your future.
