One idea away from 2/3

So I am one idea away from 20, which will be 2/3rd of the way finished.  But I am not looking at the number 30 as my magical number.
No what I am wondering about is, which of these ideas will become stories?  So in preparation for that I am signing up for more information about 12x12 (12 stories in 12 months)  and NaNo has an event in May that sounds interesting to me.
I do know that I just want to take these ideas to the next level..
