In the words of E.E. Cummings, "It takes courage to grow up and become who you truly are." You should celebrate your accomplishments! BUT remember your past, where you came from, because you can't help someone up if you're standing over them ... or constantly reveling in your own success.
Thankfully, most of my friends who've overcome their obstacles or who've grown beyond their dreams have used their journey to inspire others. They take opportunities to shine from a place of humble success. There are those on the other side, as well, which is unfortunate considering how far they come to really only celebrate alone. Because how can you help someone grow when you're always focused on your own awesomeness?
As the beautifully-inspiring founder of Utopia Con, Janet Wallace, says, "Lift as you climb." Remember this life isn't about how much you can achieve for yourself. It's how you can use your own life lessons to help others reach their dreams, which in turn, will help you! Nothing motivates you quite like seeing how your own growth/struggles/achievements inspires others. If YOU (vs your process, method, lessons-learned, etc.) are the focus of your "inspirational/motivational" movement, consider why you're telling people what you are. Is it to make yourself feel good about what you've done? Or are you actually showing someone, "Hey, this is what worked for me. It might help someone else."
Humility truly is the most attractive thing you can wear.
