If you always put limit on everything you do, physical or anything else. It will spread into your work and into your life. There are no limits. There are only plateaus, and you must not stay there, you must go beyond them.
"Be water, my friend." Bruce Lee is my hero, and this quote taught me how to be an open-minded. Never to set limits on myself, adapt to the surrounding and make it mine. The best way to live a fulfilling life.
