There are moment in our lives when everything is so clear... you can go straight to the things you want to do... and you feel so secure.
All that can be just a dream... thing can change in a blink of an eye, so we never have to relax and keep ourselves in the confort zone, we always need to have some emergency plans or at least one clear direction to get when the road gets cloudy, this way we can avoid to suffer a lot when something changes our clear and nice plan.
