A Promising Thought.

I've been tripping between what I have
what I want
and what I could have.
The three could co-exist with efforts and mutuality if I keep what I have
but the promising thought
guarantees the latter two.
However, the promising thought requires the dismissal of what I have.
The risk of losing what I have
which could
potentially
be combined with what I want
and what I could have
is tricky.
So do I go for what I want,
or make what I have be what I could have?
Desire and Greed.
It's a fine line.
