What I want to learn

I've had a passion for bicycles ever since I was a little kid learned how to work on bikes by ripping a bike apart and then putting them back together but I want to learn a lot more in how to fine tune a bike since the newer age of bikes have been released there's a lot more to learn and figure out. Want to learn a lot more about trouble shooting and to be able to give that person the correct diagnostic instead of just throwing them a false answer that could be not even right. Tools are the biggest thing on how they work and the correct way to use them I don't like half ass work excuse the language but I've had my bike worked on many times by bicycle maintenance people and charge me for the work and not having fixed correctly. I would love to work in a bike shop but you need training to do so. Some day I would like to have my own bike shop because the economy has changed so I want to be able to help out those commuters and riders to ride a excellent running bike.
