Take your ideas and put them in a spreadsheet with the following columns (factors):

The Idea, Execution Time, Likelihood of Completion, Earning Potential, Satisfaction

Give each of the columns a weighting from 1 - 5, 5 being the most important to you and 1 being the least. It helps if you do not have the same importance value to different factors.

Give each idea a value for each of the columns from 1 to 10, 10 being the best, and 1 being the worst.
