Our self-worth is not the sum of what we have done or not, said or not, felt, or anything related to our past. Nor will it be determined by our future actions, words, thoughts and so on.
We are not what the mind dictates we are or we are worth, our self-worth is beyond the mind. Deep in our heart, we are always worthy and always will be, nothing can ever alter that.
If we start from that position of always being worthy, there is less to prove, well nothing to prove, nothing to act out, not feelings of inferiority or lack, no need for comparisons with others, we can simply be our authentic real self.
It starts with a simple choice, accept that we are worthy or listen to the noise of our minds.
