Encore Careers

Keep Doing Big Things

Many people want to keep working after leaving their primary career, for reasons of financial need, personal gratification, and social recognition. Some may know exactly what they want to do, for others the unlimited options can be overwhelming. A big step here is discerning purpose from passion, and seeing how income, time, and energy are integral parts of the decision making process.
