Do not be too timid and squeamish about your actions

"Do not be too timid and squeamish about your actions. All
life is an experiment. The more experiments you make the
better. What if they are a little course, and you may get your
coat soiled or torn? What if you do fail, and get fairly
rolled in the dirt once or twice. Up again, you shall never be
so afraid of a tumble."

-- Ralph Waldo Emerson

Later, you will put more regret on the things that you have not done than on the mistakes you've committed.

Which is better, no actions or more mistakes?
