The secret to change is to not focus on fighting the old, but rather channel all of your energy into building the new.
If you find yourself swimming up river you will eventually succumb to the current and drown, don't turn back clinging to the past. Similarly, if you try to tread water and stay where you are eventually the same thing will happen. However, if you channel your energy into guiding yourself as you swim with the current, you may end up somewhere beautiful.
Life will throw change at you, this is certain, but if you can approach this change with the right mindset, you can build a life that is beyond anything you have ever dreamed!
