Yesterday I shared how the best gift you can give to yourself on valentine is the gift of self-acceptance. 
Today is the best Valentine gift you can give away to your spouse, children, family or friends.
As I mentioned you can't give away what you yourself does not have or possess, so build up your account of unconditional self acceptance and love. Once you do that you will have the ability to give away the greatest gift to others...the gift of unconditional acceptance and love.
The phases of most relationships are:
Romance phase--the person can do no wrong
Reality phase--you begin to see their shortcomings
Renovation phase--you begin to try to change them like you want them to be
Retaliation phase--anger and resentment builds up and you lash out
Rejection phase--the last phase that ends relationships is a sincere hate and devaluing of the other
The closer you get to anyone the more you see their shortcomings. The key is too stop looking for their faults, and flaws and find the many good things that they do. It will awaken the gift of gratitude and reverse the curse of criticism. Dr. Guy
