People think I'm cool - it's a virtue of my job! In real life I'm absolutely not cool, but I think if you have the courage of your convictions, and you're confident in yourself, people will maybe think that you are even if you're really a massive dork. Everyone has a different job where, to someone else, your job is really fancy!
One hard day of work proves you have heart. But day after day is what proves you have maturity and commitment.
