There are a lot of things that are uncomfortable and hard to do, and the longer you put off those things, the harder they get.

Simplicity is about clarity of thought and being willing to stay in a problem long enough to come to a solution, though it could be right in front of you.

I have two iPhones, one for day and one for the night.
