I agree with vengence here, do NOT quit your job, but studio (or what ever) gear and hope for clients to come running, won't happen. What friends and relatives say is nice but irrelevant. Enter contests, build a fantastic portfolio, have it looked at by others in the business, or actually by anybody not connected to you as friend of family.
I'd suggest to make a solid business plan for the next year, set goals and get the word out, book some jobs, learn from that. I'd love to make a living from photography but the chances to do so are not very good, and if your income is the only family income, forget about it until it actually does generate reasonable amounts of money and starts to make your regular work schedule challenging.
I'd love to get into portraits, seniors, fine art, product/food, real estate, things like that. I'd rather set my gear on fire than shoot a single wedding ever. Or some kid's party.
Also keep in mind that weddings tend to fall on weekends, ready to give those up?
Echoing all the above, make a solid business plan, have somebody look at it. Research as much as you can, try to find a pro that might take you on as an assistant (and do NOT bring your camera then, you'd not be there to shoot, but to assist and soak it all up), practice your photography, show it to emotionally uninvolved people. Try to exhibit some at a local coffee shop or something like that. Have it looked at by some pros. Join a camera club.
Just don't quit your job quite yet and be realistic about the fact that that might never happen. It's a touch business and you have to be better at selling yourself and your business than at photography. the McDonalds syndrome, great selling and marketing, crap product but very successful.
