Trying To Figure It Out

Hi, I really want to start my own business, be my own boss, make my own schedule, and blame myself when shit goes wrong. Ah yes I hope for all these responsibilities and more to rest heavily on my shoulders. I know what life I am choosing. I knew by deciding to be an artist that struggle was going to become my best friend, but you must keep your enemies closer. I don't think it will be terribly hard getting myself off on the right path, but I feel that getting the clientèle will be the biggest hardship. You put up a website with your portfolio, make it look pretty, pay X amount of dollars per month for said website, but how do you get people to bite?
Especially as a wedding photographer/children's photographer/ anything photographer. There are tons of them. Two of the ones I assist are big names. I am grateful for them wanting to take me under their wing, and not feeling threatened by me wanting to make it like them, but they have been doing this for years and I am definitely sure they stumbled at first before they got their bearings.
My point of this post is... I am still struggling with the idea of photography... I still wonder if I am good enough. Every single day when I think about it, I feel a little shaky. I get scared that I shouldn't be doing this.... shouldn't be taking photos and that I am just a failure. But its paranoia talking and negativity on my part. I lack some confidence because even though some teachers at school give me pats on the back, my classmates feel notta for the work I do. Probably because the work I do is mostly for shock value. Who doesn't like looking at naked people? Only crazy normal people.
Or so I believe.
I just hate the moments when I feel like I haven't gotten my groove when it comes to photography... I am almost there though
I'll let you know when I find it.
