"Every great developer you know got there by solving problems they were unqualified to solve until they actually did it."
- Patrick McKenzie of Kalzumeus.com
Sometimes we all just need a reminder that it's okay if you don't know how to do something. If you only solve the problems you feel qualified to solve, you'll never do anything interesting. And you won't grow enough to take on even harder problems (that you still won't know how to solve).
"Whether you think you can or you think you can't, you're right."
- Henry Ford
