The Greek philosopher Aristotle believed that courage was as virtue, meaning that is something to be practiced instead of just something you are. In other words, you can only become courageous by doing courageous things.
Every action you take is a vote for the type of person you wish to become. Ask yourself what kind of votes you are currently casting? What kind of person results from these votes?
”When longing is greater than fear, courage is born. We don't set off without longing.”
Rainer Maria Rilke - Austrian Poet and Novelist
