Try volunteering at interesting organizations looking for skills like yours. For every cause that motivates you, there’s likely to be a qualified nonprofit that needs help. Keep in mind that it might take a few attempts before finding the right fit.
You could also look for volunteer or mentoring opportunities with your current company, as a way to stay socially connected to your old job.2
You may even prefer to start a charitable organization of your own. A growing number of people age 50 and older are finding renewed sense of purpose by starting meaningful encore careers.3
