I wanted a catapult when I was young and I asked my father to buy it for me. He was a man of principles and told me that I had to learn to make it by myself if I wanted it so badly. I never made it. I continued to live with the help of others. When my son came and asked me to build him a catapult, I had to do it for him and for the first time, I relied on myself and with the help of this website. I built him a perfect one that he loved. Having understood the importance and satisfaction of doing things, I taught my son to do it too and now both of us are strict followers of the diy policy.
