MFC isn't the easiest site for beginners anymore. I speak from personal experience. No, putting in tons of hours will not help you on MFC unless you are being consistently or increasingly tipped every hour you are on cam. 10 hours and your new model status is done. You're on your own, stuck with a camscore that can take months to raise back up unless you're one of the very lucky few that make it big right away...which is not so common unless you're head to toe flawless by society's standards with an awesome personality and a great set-up.
I have a great set-up, don't know how to utilize it to its full potential yet. I'm petite and thin, but also a mom and it shows even in studio lighting. (I hear a lot of meth and crack jokes despite never touching either...) I think my personality is cool but I'm not 100% confident of my camming abilities and it shows on cam as well. I'm not great using Charlesbot and I'm not great at promoting myself on social media. I'm not good at keeping a set schedule since I'm still figuring everything out. I'm not gonna lie... I spent about $3k for all my equipment, toys, outfits, games, background, etc. I've cammed about a dozen times usually 3 hours at a time, worked 8am-12am chatting up clients, social media, research, photo Sets, editing, uploading, advertising, etc.
My 1st check from mfc is going to be less than $50 (unless I get hella famous in my sleep, but I don't foresee that happening!) So...don't let that "many models make $10k/month" thing in the MFC wiki get your hopes up. It's going to take most model's a looooonnnnggg time to build a big enough following to even rely on there being $1k/month. That's my 2018 goal... but I don't think I can do it JUST on MFC right now.
Just food for thought.
I don't want to discourage you from camming, but be open to trying multiple sites before you commit to one specifically.
