What has prevented you from reaching your goals? Is part of it fear? Fear of what? Writing it all down in private, in a journal (paper or digital) helps to process what’s going on internally. From there, you have a better stance from which to address the issue.
A journal can also help you to understand your patterns of fear as well as the things you continue to say that you want, the goals you continue to claim will be completed. Following the patterns of behavior recorded in your journal can help you understand what you fear, at what points you tend to fail and why.
Reading my old journals where I would write that I plan to do X, Y or Z, and then seeing how little of that I had accomplished was devastating. I determined to discover where I continue to fail. A lot of it was allowing fear to make my decisions, or just not making a decision at all (which is a decision by omission).
Use your journal to help you understand what you would do if you were not afraid.
