From a Barron’s online article:
Retirements must evolve because everything won’t work out as planned, says Carolyn Taylor, president of Weatherly Asset Management, an investment-management firm in Del Mar, Calif. One of her clients, who worked in the biotech industry and had a very busy family life, trained before retirement to become a master gardener. As she trained, she found that she enjoyed teaching others and finally became a teacher of gardening, Taylor says.
Retirees who feel they have no purpose are more likely to find themselves at a loss or feeling depressed, says Black. Taking on part-time work, going back to school, volunteering, or participating in philanthropic endeavors can make retirees feel that they’re still making an important contribution.
Bringing the enjoyable aspects of your work into your retirement life can be helpful, says Black. “Maybe you enjoy mentoring young people; perhaps you can find a way to continue doing that into retirement,” she says.
