Excuses come in all shapes and sizes. Many are derived from our age. He can't learn Revit...he's too old. You can't teach an old dog new tricks or so it goes. Sorry folks it isn't true. I know some old dogs who are using Revit quite comfortably. I've also met some youngsters who just don't get it.
I accept that there are learning issues associated with age in some cases. It certainly can be harder for someone to get used to using a computer AND Revit when they don't have a lifetime of using the technology. Most often it just comes down to attitude. Do you want to? I bet you can do it. Don't want to? I bet you'll find a way to make that come true.
My mother went back to school a few times in her life. After each of us (four kids) were completely immersed in school all day she took a part time job and enrolled at SUNY Binghamton. She studied language among other things. Years later she went back to school to get her MSW (Master of Social Work). Someone pointed out to her that she wouldn't be finished until she was in her 50's. She just replied, "So? I'll be 50 anyway?!?" Love my Mom, not ashamed to say it. She's always learning and age just isn't a reason not to do something.
As a wise old Jedi Knight told us years ago, "Do! or Do not! There is no try!" Even Nike ads pointed us in the right direction..."Just Do IT"! What are you waiting for? Haven't got around to it yet?
My boss at U-Haul, when I was a senior in high school, fixed that problem for me. He asked me if I finished something that I hadn't even started yet, my actual words were, "I didn't get around to it yet." He disappeared and came back a few minutes later and tossed me a little cardboard disc that looked something like this.
Consider this one yours...now go!
