@Sjcluna – there is the “1%” of society who have so much money that they don’t worry about it. So I thought your question was similar to asking what someone would do if they won the lottery or inherited a windfall of cash. If you are just asking about finding oneself at a crossroads in life, but still having bills to pay and a lifestyle to maintain, then I couldn’t change much.
My mother is retired for a few years and single, yet still lives in the house I grew up in because she can’t quite decide where she would go. She doesn’t want to live in a senior community, and she has lived where she is for 46 years, so starting over in another town, county, state, or country (even returning to the country she left at 21 when she moved here) would be such a tremendous change that it’s overwhelming even at my age.
If one is of an adventurous nature and is OK with not having the comforts of a middle-class lifestyle, I suppose it would be fulfilling to volunteer for an organization that does outreach with the less fortunate – whether it’s disadvantaged people in your own country or in other parts of the world.
