You are enough, I say this often, and mostly too myself. I believe firmly that simply because I am here, indicates that I should be here.
It is our existence which confirms that we have a job to do, something to bring and give.
The more time we spend on this fact, the more we are present to ourselves, the more we will see that it is not only you that is meant to be here, it is also everyone else.
'Saying there are too many children is like saying there are too many flowers' St Teresa of Calcutta
