He's clearly not sick of it. Harrison Ford is a bigger star than Hamill, Han Solo is at least as iconic a character as Luke, yet Ford did far, far less PR around TFA than Hamill's done for TLJ. Ford is fairly well-known for being sick of Star Wars (he wanted to die in Empire), so Hamill clearly had the option of being less involved in the PR yet chose not to.

Harrison Ford did well outside of Star Wars and could afford to walk away from it.

Mark Hamill's career hasn't gone as well. He would be foolish to not embrace it, even if he hated it with a passion.
