As an example of the person you're wanting to become let me tell you how I got there
I am a licensed cosmetologist as well as instructor, I have a whole office for my wardrobe and I repurpose and design garments as well. I also have always had a camera in my hand and now have a studio also that is used more than I ever thought it would be
Once you establish one section of your desire, you network your butt off to expand beyond that. A large part of my client base is from referrals of designers and models (fashion work) and a huge chunk of my commercial work is referrals from colleagues.
I work on production crews and as a vendor for corporations because I can deliver many skills in one person and provide stellar references when I can't be involved for some reason. The more you know, the more people you know, the more you will work plain and simple.
Thru networking you can attend and assist people you may not have access to otherwise and being a fiercely proactive business person will gaurantee that your spectacular creativity has a voice and an avenue to success
Even 20 yrs (yes someone pointed this out to me recently) I'm still assisting/learning from my peers and growing all the time!
Just my advice
