1) Are you sure you are not an Enneagram 7??
Your opening is vague. Avoiding pain is a different thing altogether than hedonism. Hedonism is self-indulgence by definition. It's pleasure above all else. By nature, it is singular in concentration. It doesn't do "balance" as balancing aspects of pleasure is not hedonism.
3) What kind of pain are you afraid of and seek to minimize?
Perhaps I might be, it seems so, based on what I just read about it. I can understand what you're saying and I do have to do painful things in my life, like recently when I forgave somebody who hurt me very badly for years out of release from the pain that it was causing me. I'll edit my profile later.
To answer your question as to what pain I'm trying to avoid is difficult to explain and I can only say that it's rejection, confrontation, and loneliness. I can only escape so much of it, but one decision of mine to avoid one of them had unintentionally hurt someone's feelings, and I'm much more cautious of my choices and do better to not make the same mistake.
To finish, I apologised to that person and they forgave me. I have some kind of balance, such as making a choice to better things for the future of myself rather than immediate choices that cause harm for the future. I recently do those types of decisions when needed to be.
