What's a long-term outcome you could get to by doing one small piece per day?

Want to see peoples' examples of something they did gradually over time to great result, system over outcome with a still tangible result

I would like to

gradually get away from my old legacy email address and have my own present day chosen and preferred provider.

To do this, I can reroute one email sender per day to the new one or unsubscribe from their list
