When your thoughts match your words, and your words match your actions, you are what we could call happiness.
This sounds easier than it is, however with practice and effort it is achievable state of being.
Any mismatch here causes anxiety. Anxiety is not a state of wellbeing to ourselves or others.
We make decisions at thought level. Therefore a good question to ask yourself, does this increase the well-being of myself and others? Well-being that we manage to create for others always returns to ourselves, we only get that well-being what we have managed to create into our environment.
