When tackling your game backlog you are going to want to follow several steps for continued success. These steps are Check-in, Evaluate, Refine, and Congratulate.
Check-in with yourself once a month to mark your progress. I write monthly progress reports on this blog.
Consider what has been giving you trouble. Is your goal too big or ambitious? Did you choose too many games to play? It may be helpful to make a list of what is working well and what is not.
Refine your current strategy by making short-term goals for the next several months. This article about Short-Term goal-setting might be helpful to you!
Take a moment to appreciate the progress you made, even if it was just a little! Also, consider why and how you did make progress, and think about how to build and focus on that success going forward!
