Distraction dilutes brain power, frazzles the nerves and results in non-optimum outcomes. The cure is to do one thing at a time. That's it in a nutshell. Do just what you're doing, and don't do anything else.
Really successful people feel the same boredom and the same lack of motivation that everyone else feels. But the difference is that the people who stick with their goals don't let their emotions determine their actions.
The key is finding the joy in between the peaks -- paying attention to the moments, to the joy in the creating of your dreams, and to the pride you feel in yourself. Even if no one else ever acknowledges what you're doing, this is the true objective.
As you contemplate making a change, I invite you to find one or more people who will wholeheartedly be on your side. Then tell them what you are up to, and ask (out loud!) if they will help you through any rough spots.
