The Wright brothers were bicycle mechanics, for crying out loud! And they built a frackin airplane! – against their own father’s religious objections of “If God wanted us to fly he would have given us wings.” Bullshit, if God wanted us to fly he would have allowed the most passionate person to make it happen.
Guess what, it happened!
The Wright brothers probably “paid the bills” as bike mechanics. What if they never followed their passion for building a flying machine, would we even know who they were as bike mechanics? No way!
Follow your passion!
