Career self-management is the name of today's employment game. Whether between jobs or not, you must continue to explore your career options, even after achieving your "dream" job. Don't get stuck in a career rut. Job security comes only from within YOU.
Research your career interests. Talk to people in different fields. Develop networks and get involved. Keep looking for ways to improve your skills and increase your knowledge. Gather data, make decisions, and plot your course to career success. Never, ever, ignore the proverbial handwriting on the employer's wall. Always be ready for the next change.
And don't forget about life/work balance. What do you need to do it all most effectively? How can you get focused with a sound action plan? Don't hesitate to reach out for professional guidance and support.
