In any area in which you want to make progress, do the thing for 30 minutes per day for 30 straight days.
Anyone can find 30 minutes in their day to focus on something they care about making progress on:
First thing in the morning
During your lunch break
At the end of the work day
Before going to bed
30 days of 30 minutes per day is 900 total minutes (i.e., 15 hours) of accumulated, focused, dedicated effort, which creates a marathon of short, manageable sprints.
