Don't always worry what your next line is going to be.

Believe that if you make courageous choices, and bet on yourself, then you will have an impact.

The key is to just get on the bike, and the key to getting on the bike… is to stop thinking about ‘there are a bunch of reasons I might fall off’ and just hop on and peddle the damned thing. You can pick up a map, a tire pump, and better footwear along the way.

Not only can you not plan the impact you're going to have, you often won't recognize it when you're having it.
