Joy
We have to put our joy on self-start rather than push-start.
If we need other people to push us to feel joy, we're doomed. We need to be able to self-start our joy, regardless of external circumstances.
The fun thing is that you are actually helping me with learning this.
I think you intuitively feel how I feel, and today, as soon as I activated my joy, even though I was still only lying in bed, you came to me and kissed me, and acted like an external reflection of my internal feeling.
