"Vision? What do you know about my vision? My vision would turn your world upside down, tear asunder your illusions, and send the sanctuary of your own ignorance crashing down around you. Now ask yourself, Are you ready to see that vision?"
Huey Freeman, The Boondocks
They say that if your dreams don't scare you, they're not big enough. I agree with that. What "they" don't tell you is that your dreams may also frighten those around you and you'll be victim to discouragement, negative energy, and hate. You'll contemplate dimming your light. You'll slow your steady pace to not lap others.
The truth is that everyone is great but few recognize it or cultivate it within themselves. When you have a vision for your life you have to dive in head first. No matter the depth. No matter the onlookers. Let them sit ashore while you tread steadily towards your goal. And it's more than ok if you aren't Micheal Phelps out the gate. You can develop the right technique, stamina, and form all while heading towards your destination.
