Impossible Goal (SL)

Hi! I am signed up for coach training in April (yay!) I wanted to make my impossible goal something surrounding this upcoming training. I thought maybe my impossible goal could be having 5 clients by the end of the year (I do think that is impossible!) But I am not sure how I could do my 25 fails in Q1 & Q2 for that goal since I won’t even be starting training until April. Do you suggest picking a different goal that I can work on all year?
