You are experiencing normal human ambition. It’s natural to want more.
The important things I’ve done to make myself feel more satisfied in my life are:
- Be grateful for the things you have. Write about them in a journal, talk about them with your spouse, etc. - Give back. Donate money to a cause you care about, get your hands dirty volunteering, do something to make the world a little better. - Recognize that you’ll never be 100% satisfied and that’s OK. Continue moving up in your career, invest in keeping your relationships strong, etc. Don’t get lazy.
