Giving to others is important.  It helps them see us in a positive way and send us positive energy.  It doesn't have to be something expensive.  You can give someone flowers.  A book is another good gift.  Even just giving someone a complement is a gift.  And when you get in the habit of giving to others, they will give to you.  Even if they just give you positive energy which is really the best gift.  Exchanging positive energy with others helps us renew and stay young.
