In the initial stages, the best is to gather information and check with experts. You can't make your choice unless you have all the info you need.
Having extra info will give you the confidence and support you need right now. Dare to go out there ask straight questions and get answers from those who can help you.
What are your options?
What are your desires, passion and ambition saying?
What are your realistic expectations?
How competitive are you on the job market place?
What are the top 10 qualities you have to offer?
What top 10 qualities do you expect from any future profession?
What does it take you to be successful with your career shift?
What are the new skills you need to learn?
Where can you get targeted training?
Who can help you or mentor you with these steps?
Take small non committed steps and gather key information. The only thing that can take you from where you are to where you want to be is action.
Enjoy!
