Critical analyse

What gave me the First year, that is critical thinking about our work, When I wrote a blog, our teacher told us, be critical to your work-evaluation, well I took this as a part of developing program ourself's, I mean this is what I did but I think I can do more and a lot better, only practising make us master of work. From a point of view now, I think this is good idea to criticise my work, because is pushing me to do better, for instance- written better in English :-)
