On a more serious note, you can expect everyone around you to go out of their way to help you out at this point in your life. They will all have plenty of suggestions on how you can spend all of your time every day. Spouse, children, grandchildren, church groups, fraternal organizations, everyone in your life will offer you endless opportunities to fill your day with all of their chores and needs.
Stand firm! Say "no" clearly and frequently! All of those helpful suggestions will be truly helpful to someone else, but eat up your days, weeks, months, and years.
Get out of bed when you feel like it (okay, when you really need to relieve yourself). Go where you want to go. Do what you want to do. Above all, never succumb to the guilt trips people will lay on you as they plan your "free time" to their wants or needs.
After 7 years of retirement I am still amazed by the number of fishing spots I have never visited. If the weather is lousy there will always be a neighborhood tavern nearby that I have never visited.
Cell phones all have a "mute" function, and voice mail is a perfectly valid way of maintaining communications on your own schedule and convenience.
I know far too many guys my age who can't figure out how they ever had time to work for a living due to schedules and chores dictated by everyone around them.
Congratulations! You worked for it, you earned it, now do your best to enjoy it.
