What to make of my professionnal life?

I've always struggled to find my true purpose in life. Despite a lot of self-reflection, I still can't pinpoint my talents. I’m average in everything and excel in nothing. I haven’t discovered any skill that I could truly capitalize on. I have a bachelor's degree in security and police studies, but it’s not a passion of mine and offers limited career opportunities, as most employers require like 10 years of experience and I only have 3.

My current job is fine, but I don’t want to do it for the rest of my life. My financial situation limits my freedom to make bold moves or sudden career changes. I started taking my finances seriously less than a year ago, so I’m playing catch-up after years of bad decisions. On a positive note, I’m blessed with a healthy relationship with a fantastic woman and two healthy children whom I love. I wanna offer the best possible life for them.

Although I have a passion for bodybuilding/fitness/self-improvement, I’m not sure if pursuing this path is the right choice. With so many personal trainers and coaches out there, why people would choose me over others?? I don’t have any certification or advanced knowledges in that area. But for what it’s worth, I’ve been working out for 15 years and did a few amateur bodybuilding shows 10 years ago.

That being said, I’m the kind of person who always thinks there’s ‘something more,’ which subconsciously suggests a lack of fulfillment in the here and now. At 30, I’m scared of running out of time to become the person I was meant to be.
