Completing the task can be a challenge. Sometimes we get started and stay consistent. But completing the task, so it is all done, as we wanted, can get sidetracked.
We might get delayed, sidetracked, see goalposts move, never quite reach the goal or many other reasons. Being emotionally involved in the process or never feeling quite ready can be other issues to overcome.
You must begin with the end in mind. Have a vision of the completed project. Prepare a celebration. Have a timeline that you follow. Have some contingency and prepare for things to not go exactly to plan. You may need to be a little flexible.
It’s hard to finish but that’s where the glory, relief and calm is.
