We have had quite a bit of discussion in several topics about the depth year concept presented here:
I intend to make 2020 a depth year for myself, having somewhat (unknowingly) tried and failed last year. I intend to write up several objectives for my depth year in the days leading up to 2020 which I will post here.
Feel free to share your own thoughts, progress, story, etc here. 2020 is the year!
