Why are you not having what you want?
- Your mind is NOT in the body. Your mind is in the past or the future, but NOT in the body.
The magic of having what you want is when your MIND in the body, working together with what you want.
Your mind wanders into the past because the past was better than now, or your mind wanders into the future because the future seems better than now; your mind is NOT happy being in the body, they are having a disagreement.
Your (ego) best friend should be your body (aligned mind and body), not your past or your future.
