Any one of us can make the decision to be happy right now. We cannot choose our emotions what we are feelings, we can choose how do we respond to the emotions. And by choosing the right responses we will inevitably feel good too in the long run. This means, happiness is in our control to decide.
By making the right choices consistently happiness is inevitable. There are even shortcuts to happiness, for example gratitude, giving and positive thinking.
Human is highly social animal, so the best we can do is to be grateful of what we have and share our happiness with others.
There is enough for everybody in this world, if we think through the lens of creating. Human creativity has created the well being that exists. Human doing is also the suffering of our planet and fellow species.
It is our next actions and decisions that determine what will follow. Therefore we can be happy with what we have now, contemplate on our virtues: what are we willing to sacrifice for our future?
We get only that well being which we are able to create for the world.
