sheetalb: sorry for my stupid long useless advice. of course if you have the energy and interest anything is achievable. in no way was i discouraging you from getting trained (if that's what you want to do). i know of a chinese guy who was a computer guy and at the age of 35 went back to school to study medicine and became a doctor. so go for it... get trained and all the best for your future. just ignore my postings. - midwestdude
