You will not regret.....

At the end of your life, you will not regret .....

not having your promotion;

not winning another argument;

not having one more trophy;

not watching another TV program;

not having all things be perfect ;

not having bigger savings in your bank;

not spending enough time in the office;

not having another pair of shoes or latest designer handbag;

not having that luxurious car and bigger home that your friend has;

not having that latest gadget that your neighbor has ....

But you will painfully regret if u have not spend meaningful, undivided  simple yet imperfect time with people who matter most. 

Take time for your children , your spouse , your parents, your siblings , your friends . ;)
