Congrats.
Anybody who tells you that you need to stay busy is wrong
Retirement means you deserve leisure, so enjoy
In my experience, those who have retired and feel compelled to keep "doing something" are usually folks who are trying to distract themselves from the question, "What is my purpose in life?"
I have a friend who retired and then got another job....I have coffee with him weekly. He despises working but justifies it as keeping his mind busy or other bullshit excuses. I think he works to stay away from his menopausal wife and also to distract him from how he finishes his twilight years on this marble.
I retired 6 years ago and not by choice(medical reasons) but I am figuring out now......the toughest part of retirement is being content doing whatever you want guilt free. "Hobbies, bucket lists, etc" are only distractions in my opinion to avoid asking and answering the question, "What is my purpose now?"
Read "Life Worth Living" and "Ruthless Elimination of Hurry"
That will keep you thinking
Congrats!!!!!
