The way to find proper enjoyment is through wholesome activities. Some people may choose to get involved in home improvement and repairs. One retiree told me he is glad whenever his wife tells him about a leaky faucet or something that needs fixing. Some people choose a hobby. Others find great delight in golfing or fishing or watching sporting events.
Many hobbies are available even for people who are confined to their homes.
Find something you can enjoy and spend some time doing it. The third essential element in handling the time afforded by retirement is that of reaching out to others. For Christians this can be an effective way to witness. I know an elderly woman who is a good cook. She looks for opportunities to bring in meals to families where the mother is ill or hospitalized.
