I'm not one for resolutions. I personally find them to be to nebulous. "Lose weight. Write more. Spend less." They're fine aspirations, but what's the plan? How is this going to be achieved?
Good goals should have a defined end point. For example during National Novel Writing Month the goal is to write 50,000 words. An experienced goal setter will give themselves milestones before the end goal, and that's exactly what NaNo does, splitting up the goal into daily milestones which can be celebrated each and every day.
Good goals should have a time frame. In NaNo a writer is attempting to write those 50,000 words in one month. I find that choosing a time frame is the hardest, and most important, part of setting goals.
Successful goals include some social accountability. On the NaNo website your total word count so far is posted under your username on every post. Everyone on the site knows if you're ahead or behind and it can encourage writers to finish their words for the day before posting.
There is one more thing one can do to make goals more likely to be successful, but I don't even do this one.
Successful goals stake money on the outcome.
Our company goals for the year? (By posting them here we'll get some social accountability!)
1) Publish a new anthology before November 2018.
2) Attend one new marketing event a quarter.
What are your goals for the year?
