Why we do not fulfill promises that we keep to ourselves? This seemingly simple question has very deep link with our psyche.
Fulfilling promises is a matter of integrity. Integrity is doing things as we had said.
When we say some thing, how much we shall do it completely or a part of it or extent of that what we said is a function of how much we value our words.
How much we value our words is a function of how much we value our own selves.
How much we value our own selves is a function of how much we love ourselves.
How much we love ourselves is a function of how much willing we are to grow mentally and by spirit.
How much we are willing to grow is a function of how much we have became disciplined and how much we have learnt to tame our easy-self, the part of us which is never ready to put itself in a difficulty or wich is always seeking escape routes from tough situations.
We only break promises with ourselves, when we do not value ourselves enough. There may be multiple of superficial reasons or obstructions may come in fulfilling our words, but there is one reason lying underneath: we do not value ourselves enough, we do not love ourselves !
