One is enough. You do the 7-steps on one goal at a time anyway. If you have more than one goal you need to further prioritise what you are going to work on first.
Clear Mind Bright Future gets you to pull up heaps of goals and then select 3 from from 3 areas of life ultimately reducing to one from each and then gets you started on a plan of action on at least one for the next 30-days.
