Same as for anyone else: be intellectually humble. Your reality is not the only valid reality, and you'll have many experiences where you feel 100% certain about something and then realize you were wrong. Stop being 100% certain and start feeling proud of each of those experiences, because some people are too afraid to acknowledge them.
Have a long-term purpose (what is purpose?). Stay away from toxic people, especially in love and business (what is toxic?). Wait a little before having kids (what is responsibility?). Travel widely (what are your limits?). Read good books (what do you not know?). Devote solid time to your hobby (is there purpose apart from work?). Cook for and entertain friends (where does your soul dwell?). Appreciate and practice your preferred sports and arts (what fuels your soul?). Enjoy life (why are you here?).
