The one who wins is the one who sets his/her goals on something past the finish line. This is because the finish line is often not in the proper place, sometimes it is altogether too close or too easy to achieve. For this reason many people never become better than what they are currently getting.
There are countless lessons to be learned from the adage of stepping out of the "comfort zone", but exactly what does that mean and how is it achieved? - Just one thing at a time. When a new idea comes to mind, try it. When a new technique is discovered, use it. When it feels weird, do it any way.
If no one else is doing it, continue doing it. Unless this new thing is certain to kill you, it will only make you stronger, better, more productive, or successful in an area which you were not previously successful. The comfort zone is designed to keep you down, to stall your growth, and keep you unsatisfied. In reality, the comfort zone becomes not comfortable the longer you stay in it. Try something new. You just may like what you get.
