My wife a schoolteacher very disciplined. If you think I'm tough trust me and wait till you see when the children are on the naughty step. It's hilarious. So we decided that I'm going to work like a donkey and provide amazing support for the family.
Take those chances and you can achieve greatness whereas if you go conservative you'll never know. I truly believe what doesn't kill you makes you stronger. Even if you fail learning and moving on is sometimes the best thing.
