Persistence

Albert Einstein said, "I'm not so smart. It's just that I stay with problems longer."
This is a great quote because it just affirms that you do not have to be the best or smartest to succeed. Persistence can prevail over natural or learned talent or intelligence. It is a great reminder to me that I can still achieve great success if I just keep working at it. If you find yourself stumped on a problem, or maybe just stuck in a rut, keep pressing on.
There is always light at the end of the tunnel.
