I’ve never seen or heard of any credible case of someone growing nearly a foot in height after puberty. It’s so improbable that one might as well say that it’s impossible.
Most of the other things you’ve mentioned can be done easily:
Become smarter: Many people have done this already.
Master skills: There are lots of subliminals for this.
Increase empathy: Yes, you can do this. Many people have done this.
Improve health: Again, many people have done this already.
You can improve your life on practically every level with the help of subliminals. Wealth, relationships, sex life, health, intelligence, social life, physical fitness, skills, etc.
