I am a triple Diamond and this would be my 4th time doing the Impossible Goal. How about that!
I joined back in January 2017 and set up for myself an impossible goal each December.
Each following December I realized I did not accomplish the goal itself (they were all winning a contest of some kind) but I learned a ton and I changed as a person while pursuing the goal.
This year I thought perhaps I should choose a goal that its result depends on me and not on someone else deciding whether my yearlong of work was good enough.
Would love your thoughts.
