Who decides what they are and how to check the box? To make progress and count success there has to be a reference and reality based view of the gaps.
Tasks are not milestones. Days are not milestones. That said, each of these can be a milestone marker when combined with other factors.
After I succeed, the world decides that it was so simple. Everyone could have done that they whisper and shout. Reality is that this is not true. I saw it. I set out to do it. I asked for help and gave help and had good days and bad. It is the sum of the total effort that allows me to track success.
My milestones for 2021 were not as fixed as I like. Fluid days, fluid, even volatile moods and methods generated action and results. The milestone is checked. 2021 DBD… Deciding success or failure is TBD.
