I know I would have a difficult time telling an older person to do this, do that, get this, and get that. I would have to predict that the first 2-3 years would be the most difficult. Making dumb mistakes is easier to take when you are younger. As you get older there is less leeway (sp?) to make dumb mistakes.

I wouldn't want to discourage anyone from getting into this trade, but these are a few of things I can see happening early on. Give 'em hell, and best of luck to you.
