Any time you feel like you’re on shaky ground with some meaningful challenge you’ve taken on, talk to yourself like you would talk to a toddler learning to walk: “You’ve taken the first step. You may feel wobbly now, but you’ve begun. You’re going to get there.” And remind yourself that every great achievement is rubbish at the beginning. Every one of them. As the Irish playwright George Bernard Shaw once said, “A life spent in making mistakes is not only more honorable but more useful than a life spent doing nothing.”
