Work takes at least 8 hours of your life per day, so you should be really passionate about it, to be sure you invest your time wisely.
I had a couple of realizations in my short career: One is that if I wait until I feel ready to do something, it will be too late. The second is that it’s actually very easy to lead an extraordinary life - you just need to be willing to do the things that others are not. The things that are a little too hard, take a little too long, or are a little too uncertain.
Professionally and personally, I take more risks, do things without worrying about how I might be perceived and start down paths without knowing where they could lead.
When you do what you love, people rally round you. Enthusiasm is contagious and you attract other people who are passionate too. Life is a grand adventure, or it's nothing!
