You are not selfish or ungrateful for wanting more for yourself. You can appreciate where you are, what you achieved, and the ways you've grown while still admitting that this isn't all there is for you. Drive doesn't always have to be fueled by dissatisfaction. Sometimes, it's fueled by a desire to experience more, explore your potential, and meet new versions of yourself. So, don't listen to people who tell you to just be happy with what you have. Gratitude and ambition can coexist.
