There are many different tips on getting your output up, but the truth about this here author (me) is my goals change and fluctuates based on what is happening in my life. For instance, this month is Christmas, I have a LOT to finish in time for Christmas, dollhouses, clothes, quilts, not to mention preschool for my daughter and babysitting off and on. Frankly getting stories out-while still a major goal-has been reduced to only a few thousand words per day.
My goal of hitting 50 books this year is being pushed back to 40 - and I'm well on my way to that (book 37 and 38 are at the editor now!) The key for me is to set goals I can accomplish, and that means if I have one that is becoming too lofty to reduce it into smaller portions. I will still hit 50 books - but I have given myself until March to hit it, allowing me the opportunity to be with my daughter and enjoy the festivities, and to produce quality.
So keep ACTIVE goals, goals that work around you and help you feel accomplished. Work continually and do do do!
