Say you would like to finish a quarter of a million new words this year. A very solid, but scary goal. A very large elephant.
1…. So divide the total word count desired into 50 weekly parts. (Two weeks off for vacation.) Example: 250,000 words divided by 50 weeks = 5,000 new words per week.
2… You have determined you can do about 1,000 words per hour. So divide the 5,000 words by 1,000 = 5 hours of writing per week.
Aim high, then chunk down your goals into daily tasks. You can do it. :-)
