Don’t EVER let anyone strangle your dreams. You can become who ever you want to be. An astronaut, an author, anything. Just have faith.
"Then indecision brings its own delays, And days are lost lamenting o’er lost days. Are you in earnest? Seize this very minute; What you can do, or dream you can, begin it; Boldness has genius, power and magic in it." -Johann Wolfgang Von Goethe
"The confidence of ignorance will always overcome the indecision of knowledge." -Unknown
Those who risk nothing, gain nothing. To settle for safety and security insures that you will never have more than what you started out with.
