Not everyone is a teen here, and not everyone here is without experience. They may not have the experience in voice coaching or acting, but they sure have experience in Performing. And there are some who have gone the mile, come back, and gone again with new insights worth evaluating. There are some who have gone way past your performing experience (not career, don't get that mixed up), way past what you have tried and dare not try - who have listened, tried, thought hard, have been brutally honest with themselves, and have returned with golden nuggets for those with the potential. There are also those with the critical eye, who have seen the good and bad, and have the clarity to DISTINGUISH these good and bad.
They may not know everything about Magic, they may not have reached the highest pinnacle of performance, and they can damn well be no better than anyone else - but they have principles, integrities and are mindful of all these which they keep. You should know, its not the man himself, but the work of the man which says a lot about what, who and how they are.
You may be experienced in many things, but where is the proof in the things you show? Even though you have the higher education compared to most, how do you know you are not doing exactly what you loathe them to do, but in a different way? Worst of all, even with such qualities you aquired?
It is good, to take the knowledge and insights of others and shape your own path. Mold it the way you see fit, no one has the right to tell you how you should walk this path. But, when you take that leap and share it with the world, remember it should be of fine quality.
A person like you should understand this.
