And it only took him 17 minutes to fix each one! Before moving to another city, I begged him to teach me his techniques , as I still had constant headaches with my own computer. He agreed, teaching me the step-by-step checklist he uses to fix people's computers . I couldn't believe how easy it was! With his list, and another two years collecting all the tips and advice I found, I revised, refined and simplified my own techniques to keep my computer in optimum shape. I have a notoriously bad memory (just ask my wife), so if some computer problem again happened down the road (which it did), all I had to do is go back to all the notes I collected. Viola, problem fixed! Then one night I got a call from one of my clients complaining about his slow computer . Since I was his web designer, he figured I was the "computer guy" to call. I fished out my notes and took him step by step through the techniques that worked for me, in the exact order that from experience I knew worked best. The phone call lasted twenty minutes. And guess what? He emailed me the next morning thanking me and offering to buy lunch. His computer was completely error-free and blazing fast, just like new!...
