One of my main issues I wanted to address when I started therapy in the first place was very annoying procrastination tendencies and creative blocks (writing was the main area for me as well, my field is scientific/technical primarily). About two years (and two therapists) later, I am happy to see very significant improvements. I did have to make my own hard efforts, but therapy was helpful in these areas even in some quite unexpected, unforeseen ways. One of my biggest improvements definitely. It was important to look at what caused the blocks and procrastination in depth but then also equally important to force myself into action in spite of the blocks for a while, to learn not to let them hold me back.
