There are no guarantees in life, but it is a sure thing that you will get back what you give.
If you give 100 percent of your attention, energy and time to something, you will get exactly that back.
Spending your time and attention focused on what you cannot do and do not have, assures that more of the same will come. When you concentrate on emptiness, weakness, fault, and blame, it is sure to become a reality.
Nobody has everything, but everybody has something. Use what you have right now. Use it wisely, freely, with love. Wherever you are, use your time, energy and talents to do the best you can right now. Give no thoughts to what is missing. Spend no time wishing it were better. Make sure you give all you have, to make sure you will get all that you need.
