Make your own tracker. Depending on what you want to include to track. You can do it daily, and you can do it weekly, depending on your preference. What matters is at the end of the challenge or on your updates, you can see how well you have improved and how much you have actually earned and compare it to the days you did not do the challenge. I guess that is how you determine your success and how you can actually "COMMIT" to doing something Steemit.
