To be or to do

So, I am working through two words: being and doing. Both are 'ing' words, which denotes action or process....

Being means 'to be...the quality of having existence, or essence.'

Doing means 'to do....the act of performing or executing.'

These are very small words...be and do.....but they are powerful.

So, what defines me, my being or my doing? Why do I feel that unless I am doing....producing something....that I have no worth. Where does a person's worth come from?
