Being brave is a all about practice. It's not about big leaps (though by all means, leap!) - instead try small acts of courage. Trying a little new thing, asking for more dollars for a project, talking to someone you normally wouldn't connect with.
Practice bravery every day and I think you'll be pleasantly surprised at how easy it is to live a bold, brave life. Yours in this squirrel doing wrecking ball, Kelly
