Bad decisions or remained indecisive
You have now written about the future you would like to have. Clearly defining your future can help reduce the uncertainty in your life, and reduce the amount of negative emotion that you chronically experience, in consequence. This is good for your confidence and for your health. Having well-defined goals also increases your chances of experiencing positive emotion, as people experience most of their hope and joy and curiosity and engagement as a consequence of pursuing valued goals (and not, as people generally think, by attaining them).
It can also be very useful to deeply imagine the future you would like to avoid. You probably know people who have made very bad decisions and who end up with a life that nobody would want. You also likely have weaknesses yourself. If you let those get out of control, then you might also end up with a miserable, painful life. Most people know how their life could go downhill if they let it.
Spend some time, now, thinking about what your life would be like if you failed to define or pursue your goals, if you let your bad habits get out of control, and if you ended up miserable, resentful and bitter. Imagine your life three to five years down the road, if you failed to stay on the path you know you should be on. Use your imagination. Draw on your knowledge of the anxiety and pain you have experienced in the past, when you have betrayed yourself.
Think about the people you know who have made bad decisions or remained indecisive, or who chronically deceive themselves or other people, or who let cynicism and anger dominate their lives. Where do you not want to be?
