I think a better title would be Isolation and the Art of Being Decisive About It or Aloneness and the Art of Being Decisive About it. I searched for a quote for you because I don’t think you are describing loneliness because you are much too content to be alone.
“Loneliness is a lack, a feeling that something is missing, a pain, a depression, a need, an incompleteness, an absence.
Aloneness is presence, fullness, aliveness, joy of being, overflowing love. You are complete. Nobody is needed. You are enough.”
