Aside from my lifelong goals, I have broken down my goals into a two-year plan as well as a quarterly. I write out new goals at the beginning of each quarter, depending on what I accomplished the previous quarter, but I suggest reviewing those goals daily. Put them up where you can see them. Because it's easy to forget about them.
This is exactly what occurred to me this past summer. Yes, I got lazy and forgot them.
Now, I didn't exactly forget them. I still wrote, just not as much. In fact, the current work-in-progress then stagnated and stalled altogether.
Then I got the energy to start a new story and I'm currently around 7,000 words into it. I don't know if this will be a novelette or novella, depending on the word count, but it's been fun so far.
Keep your daily goals in sight.
Review them. Add to them, if needed.
But always push yourself to complete them.
