OP, remember to always be the Captain of your own life. In this case, that means not being steered into the wrong direction by outsiders.
Lots of good advice here, knowledge is great, keep learning, and remember that not all instructors are good, or bad, but you have to find the right person for you.
Don't be railroaded into taking someone because some flight school said "This is going to be who you get". Probably nothing else along the path to becoming a Pilot is more important than YOU picking out the right instructor for you.
We all make choices, some people will agree with you, others will tell you that what you are doing is all wrong. Again be the Captain of your own life. Many people tried telling me to just follow the path most others took to becoming a pilot. I didn't, but did it my way, I was 18 then, turn 49 in a couple of weeks, and zero regrets looking back. I put as much effort into picking my instructor, as I did into what airplane to purchase, because both could help make or break how it went. School one I went into, they had two instructors, neither one was even close to what I wanted in an instructor. Drove down the road a ways, got to school number two, it had a much better vibe, the lady who greeted me showed me around the place, friendly, answered my questions, and introduced me to the only instructor who was there at the time. We chatted some, he took me out to the ramp and told me how they work, and as we talked, the owner/instructor was just taxiing in, I got the opportunity to meet him briefly. Back inside I was offered a coffee, and to wait for their third instructor to land, and meet her. It gave me the opportunity to meet several students who were flying with them, and eventually the last of their three instructors. I left there feeling great, drove down to the last school at the airport, it was somewhere between schools one and two for the feeling I got from them. I met their two instructors, and the one had a short opening in his schedule, so I took them up on their offer of a short familiarization flight. It was "okay", but not the right fit for me. I drove back to school number two, was again greeted warmly, and I asked when I could schedule a familiarization flight with them. She looked over the schedule, and said that evening the owner was available to tske me up. I left and went back many hours later, had a pretty good flight in their warrior. I was asking him about the lady instructor on staff, I met her for only t minutes, but she and I seemed to click. He offered up some information about her, and said that when we land he would check her schedule. Well I booked another familiarization flight with her for the following evening, we went up in their 172 this time, and I knew 3 minutes after we took off I had found my instructor. Now I told her that I had bought a 172, it was in getting some work done, but would be ready to fly soon, and asked if she would like to be my instructor. She replied " Heck ya, I would love to do that ". Done deal, and we flew often, I a few times flew with the other two guys there, partly because I like to get others opinions and skills, but also sometimes I just really wanted to fly and she was busy/sick/away, but primarily I flew with her. We often flew in the evening as her last flight of the day, and would then grab dinner together, we became friends as well, and she is still a friend to this day.
Long story I know, but pick the right person for you, and don't let some stranger decide who you will get stuck with.
