We all like to win, but what happens if you don't? If you are as competitive as I am, it can be really hard to take a step back, look at the big picture, and see that this one loss or setback is not the end of the world. Sometimes a loss provides us with a wake up call or clarity about what we need to work on, improve, or change. If you have the right outlook or frame of mind, it can be a brand new starting point to keep moving towards your goals.
Surround yourself with people who believe in you. Even better, never stop believing in yourself.
