Are you financially secure? Take a close look at your budget. Ask yourself some tough questions.
The path that you must take is before you. There are no signs, no passers by to advise you, and not much else to help you but your own intuition and the facts that you have gathered. We all find ourselves in this situation at times, where the only other option is to turn back. Some things are destiny and some things are duty. Only you can decide if you're willing to roll up your sleeves and tackle this new challenge.
It's a Google world, and potential employers now routinely search for information on job applicants online. If you have a strong presence online, make sure that you curate what you post and control the message you're putting out there about who you are.
