The fastest way to your own happiness is to make another happy.
Thinking happy thoughts literally creates a positive chemical change in the brain which stimulates both positive physical and psychological benefits.
If you want to be happy, make someone else happy. If you want to find the right person in your life, be the right person. If you want to see change in the world, become the change you want to see.
The ultimate goal of all goals is to be happy. If you want to be happy make someone else happy.
Be happy for no reason, like a child. If you are happy for a reason, you’re in trouble, because that reason can be taken from you.
Not every sky will be blue and not every day is springtime. So on the spiritual path a person learns to find this kind of happiness without needing nice things to happen on the outside. Rather, you find happiness by being who you really are. This isn't mystical. Young children are happy being who they are. The trick is to regain such a state when you are grown and have seen the light and dark sides of life.
