We should learn to worry a little less, do our best, be clear in what we want and don't want - but really, we should try to worry a little less.
If something is really worrying you, cut to the chase.
Figure out WHY.
Know what is within your limits to do something about.
Know what is without.
Know what you will do, if the worst occurs.
Know what you will do, if the best occurs.
Then let it go - until.. either or other occurs.
If we hold on too tightly to a particular outcome, we are not acting in our own best interests...
Wasting time and precious energy worrying... is it really worth it?
