OK....so you have a plan and are ready to move forward and WHAM.....something unexpected happens.
What do you do now?   Well one thing is for sure, you can't throw your hands up in the air and move away from your path.   Things happen and sometimes they don't seem to make sense, you might get frustrated however you need to keep moving forward.   Take time to reassess your situation, and make any type of  adjustment to your plan....then get right back on your path....don't waste another minute as you have work to do, making your life better.
