First, congratulations on going the entrepreneurial route! You have a situation that is very common and one that can cause frustration so you're smart to identify it early.

Branding, skills and experience are all external to you. They are the building blocks you use AFTER you've determined the type of business model that would work best for you personally. Here's are the first two steps in how to start:

1. Identify your values. (not strengths - that's external). Values are internal. They are the things that are most important to you. For many entrepreneurs, the values of Freedom, Accomplishment, Creativity, Recognition come to the top of the list. There are no right or wrong answers - only what is important to you.

2. Once you have your values identified, it's important to know your personal style - your way of being in the world. Are you introverted or extroverted? A mixture? (By reading your question I'd say both). Go toward pleasure? Away from pain? Want to help others?

Consider these items above or get a personal style test and values test to know quicker.

3. Once you know who YOU are and what drives you, you must build a business model that can serve what you want to achieve in not just business but life. Do you want to be a solo person doing all the work? Run a large company? Somewhere in between? Online or offline or both? Then compare your intended business model to your values and style answers. Now when you ask the "Should I" questions you'll have a blueprint to help you make the right decisions every time.

Hope that helps.
