Keep going. The idea is to go on and not analyse at the start. Remember if you're not happy by the time you've finished you can start over.
When I did the couarse in 2003 I had no clear purpose for my life either but I went onw with what I had and for the first time in my life a goal setting program yelided results. Withing 6 months my three main goals came into being and by the end of the year they were all set.
So I suggest you keep going don't analyse the conscious mind only handles a small part of your thinking. Go with what comes up without analysing too much.
