The image we have of happiness is usually confused with financial comfort. You have money, you are happy. Everything is fine... Everything is fine?

No. Financial comfort, although it can offer pleasures, and is certainly welcome, essentially diminishes joy, softens, cancels our ability to fight to live.
Because the effort to overcome the obstacles of life as well as the need for creation are essentially emotions that bring fulfillment.
They empower us when we stand tall.

When we fight and win battles, when we fall but rise and continue, we build ourselves, we make ourselves giants, we make ourselves a strong support of our inner world.

Also, our contact with Nature is stimulating, therapeutic. Jump, run, dance, sing, celebrate! All these bring joy.
Accept life as it comes, discover the natural flow of things, teach your children to gracefully face difficulties and obstacles.
