You alongside a lot of other people don't have anything nice to say, it costs $0.00 to be nice. I am sorry if you are having a tough year and want to take it out on me. Remember, someone took a chance to you. You grew with age and experience, and what sounds stupid to you, probably wasn't when you were my age. So remember your early days and don't comment if you shall not want to.
I would caution here. I can't speak for everyone, but while someone indeed did help me learn the ropes, they were far less convivial then what you have received here (and they were family and I started when I was really young).
I remember I was in an embroidery forum and a person was wanting to get into sublimation and I had asked if they had done a C/B on what it would take, how long would it take to be profitable, updated their business plan etc. Someone else came along and said don't listen to the downer and just do what you want. A year later they were getting out of the sublimation aspect of their business. Take what you want from that.
When you ask a question, you open yourself up to all kinds of comments, even from the crusty ones, there is something to learn. The question is what do you do with it? When dealing with the public, you are going to be deal with all kinds of personalities, some you really won't like. How you deal with them, how you defuse the situation etc could go a long way with your business or a very short way, all depends on how you choose to conduct yourself.
Take what you want from the answers here, but quite a lot of users on here have decades of experience, I wouldn't quickly dismiss it, just due to the delivery happens to be dry and crusty. Read it, absorb it, then decided to keep or discard it. I can tell you, someone that can still listen and have a conversion with someone that they disagree with, but still see that there is something there to have a conversion about will go further then one that just shuts down and dismisses it.
But that's just my take on it.
