Look at everything in a loving way.
Love is never between two people. Love is something that you have inside you. Love is quality, not something you do with someone else. If you notice this, love will grow within you.
Sit for 15 minutes every day for a few days with something: a tree, a worm, or an insect.
After a few days, you will find that you look upon it with as much love as you have for your wife, husband, kids, or parents.
Instead of looking for love outside yourself, practice feeling love from within.
Love is something that you can grow within you, not something between people.
