Find and keep close mentors who have time to give you advice, find topics and books you're drawn to and keep an open mind. I found that a lot of my foundational skills that drew me to my passion career (journalism)) in middle school, high school and college were inherent in me and I brought those strengths or attributes to new jobs (diligence, detail orientedness/fact finding, curiousity, fighting for underdogs, connecting the dots and seeing a big picture and telling a compelling story to meet an objective.
So you will find that your strengths are threaded through your life choices, whatever job you choose as you will also be called to those jobs. As you continue your journey and enjoy that and leverage that. But sometimes you need to make choices that help pay the bills and support a family and there's no love lost for passion projects there by doing that, I find that's the myth of blankly saying "do what you love" because if it's not enough to sustain a quality life, you will no longer love it.
Ultimately, having your own shop carries with it its own risks. Work for others and really observe and learn the in's and out's there before striking out on your own. Certifications are good, but DOING it is the only place where you learn. Good luck!
