Getting motivated is half the battle, getting to work the other.
I spoke to a fellow who retired several years ago like me and suggested we get a club together. We would meet once a month at a members house and get their "honey do" list done. We would then go to the next house the next month. Wives would have to agree that their work days would be coming in the months ahead but it will get done for sure. We could pull names out of the hat each month during our guys out lunches, plan the work and supplies and get to it the next week.
This might just motivate us all.
