I think I would do what I can to be of service to others. Over time, that would take me everywhere I want to go and it would lead me into places where I do everything I want to do. The key thing in living forever is meaning. You have to make meaning out of your life, for you now have the greatest of all the greatest gifts in life: a life with no end.
People are even more important when you live longer. Love is more important. Making new friends is more important. Maintaining intimate contact with individuals and with humanity itself will be essential. Otherwise you will soon feel like an alien, and will be desperate to give up your immortality. Humility is key to all of this.
