Tell your story: yes, tell your story! Give your example. Tell everyone that it's possible, and other people will then have the courage to face their own mountains.
Keep away from people who try to belittle your ambitions. Small people always do that, but the really great make you feel that you, too, can become great.
She is coming, my own, my sweet;
Were it ever so airy a tread,
My heart would hear her and beat,
Were it earth in an earthly bed;
My dust would hear her and beat,
Had I lain for a century dead;
Would start and tremble under her feet,
And blossom in purple and red.
