let it go

We will feel unhappy just as we don't do the thing well.
We will feel unhappy when/if we don't do something well.
We will feel unhappy when we fail to do something properly/correctly.

Or when we do something wrong, we are used to blaming ourselves.
Or when we do something wrong, we usually blame ourselves..
Or when we do something wrong, we often blame ourselves.

Actually, others just blame us one time [once = one time] or
even they don't care abouot what we have done.
they don't even care about what we have done.

But we blame ourselves more that than one time.

It seems that we always forget to forgive ourselves and forget to let it go.
