I thought I would have the same problem, but I retired in March at the age of 53 afterr 25 years in a stressful job. I thought my life would be boring, but it seems I always have something to do. I have a woodlot and cut wood, and just puts around the house. It is so nice to be able to do what you want when you want. Don't worry, you will get used to it, and enjoy it.
