What if you had been raised believing that happiness has nothing to do with your external circumstances ?
How do you feel about this proposal ?
Appalled ? Enraged ? Suspicion ?
Good ! Love your reaction until it fades and then move on to testing this proposal. Meaning that you regain freedom about feeling the way you want while you experience life. Meaning that if something happens to you, good or bad, there is no preset way to feel something as a response.
Practice makes perfect. Keep me posted on how you tweak it.
