Love is what we should all strive for. Love is what makes the world go round. What are we without it?
The need to love and be loved produces a lot of good things physiologically. Love can come from many different sources. We feel love from our parents (most of us), love from siblings (hopefully), friend(s) and hopefully from our partner/spouse.
We can also get love from hobbies and activities. Ultimately we need to love ourselves and put ourselves with the people who love us and the things and activities we love to do.
