People often say that you have to open some doors to get somewhere in show business. Actually what you want to do is open some studio gates. When a few gates in Los Angeles opened for me on a regular basis I knew I had arrived. It was a good feeling, scary sometimes but good, my hard work and years of sacrifice had paid off. NBC was saying,
"Oh yes Chili Challis come on in!"....That's what's up! ;)
Don't look at anything as a closed door. There's no such thing. Invisible doors don't exist.
