Here's the simple truth - you need to work at it. Period. For most things related to learning to play a musical instrument, you need to put in a lot of focused time in the practice room, and I'm not talking an hour or two a day for a couple of weeks, I'm talking an hour or two a day for several years to develop, and then for the rest of your life if you expect to maintain it.
There are a lot of people in this thread, myself included, who have made their living, or are making money with their horns, and there is a reason for that - we've put in the time to develop our chops, technique and musicianship to a point where we can. I know in my case, while certain things did come naturally for me to a certain degree, I also put in thousands of hours in the practice room and in rehearsals, and that was before I took my screening audition to get into the Army band program back in the autumn of 1988. Since then I've put in quite a bit more time. Right now I'm typing this to you from my practice room where I've just gotten done playing long tones as part of my warmup - long tones that help to maintain strength and focus in my embouchure so I can continue to get paid for gigging. I practice what I preach.
I apologize if the wonderful advice you've received all throughout this thread wasn't quite what you wanted to hear, but you might want to take a few minutes to re-read this thread, reconsider what has been said, and apply some of it - especially that bit about getting a private teacher to guide you through some of the stuff you'll need to do in order to better develop your chops.
