It is very important to write down your goals. When you write them down, you help yourself fine tune and clarify what you really intend to do, and it strengthens neural pathways in the brain related to your desires. This process is necessary for your success.
However, in writing, you have to be as concrete as possible and jot down how you want to implement your intentions to accomplish your goals. For example, writing “I will start exercising this year” is not a very specific goal. Instead, write “Every 5 p.m. on Mondays, Wednesdays, and Fridays, I will put on my running shoes and run for at least 30 minutes.”
