Time for a change?
Once you've discovered (or rediscovered) your passion, spend some time researching the types of careers that center around your passions. Don't worry if you're feeling a bit unsure or insecure -- it's a natural part of the career change process. How much research you do also partly depends on how much of a change you're making; for example, changing from a teacher to a corporate trainer versus switching from a nurse to a Web designer. You can find some great career information and a skills-matching service at O'net online from the U.S. Department of Labor and basic job information from the U.S. Bureau of Labor Statistics'.
Transfer your skills
Leverage some of your current skills and experiences to your new career. There are many skills (such as communications, leadership, planning, and others) that are transferable and applicable to what you want to do in your new career. You may be surprised to see that you already have a solid amount of experience for your new career.
Training & Education
You may find it necessary to update your skills and broaden your knowledge. Take a course or two to ensure you really like the subject matter.
Remember that, in a sense, you are starting your career again from square one. Obtaining a part-time job or volunteering in your new career field not only can solidify your decision, but give you much needed experience in your new career. Work odd hours if you have to just to gain experience.
Assessment of Likes and Dislikes.
A lot of people change careers because they dislike their job, their boss, their company. So, identifying the dislikes is often the easier part of this step; however, you will not know what direction to change your career unless you examine what your looking for or what you like.
One of the real keys to successfully changing careers will be your networking abilities. People in your network may be able to give you job leads, offer you advice and information about a particular company or industry, and introduce you to others so that you can expand your network.
Find a Mentor. Changing careers is a major life decision that can get overwhelming at times. Find a mentor who can help you through the tough patches. They can help you be successful.
You'll need to be flexible about nearly everything - from your employment status to relocation and salary.
