What have you learned from one of your mistakes while working as an IT support specialist?

"I am very careful and try to avoid mistakes; however, they do occur. When I do make a mistake, the first thing I do is resolve it. I then look back on my actions and try to figure out what I could have done better. I always try to turn a mistake into an opportunity to learn and improve my performance. The greatest lesson I learned from my mistakes while functioning as an IT support specialist is to actively listen to the end-users when they describe their problems. Many of the mistakes I've made were because I assumed I knew the answer before hearing the full description of the problem."
