Knowing yourself weaknesses you become stronger

Many writers/philosofers tried to build a model of really successfull people. They researched bios of great humans and than tried to found same in character traits, type of thought. For me, I think its critical to know own weak sides. When you know your weak sides you can concentrate on what dont using your weak sides. You can find a best areas for you character, skills. One of managment classics, Peter Druker, were saying that we need to improve our strong sides and its really more important and will give us better results. For example i am not ashamed to be acknowledged that i havent enaough discipline to work intraday now. Maybe its just because i havent chances to concentrate only on this. I understand it fully that at least i will not concentrate only on daytrading i will lose money on it. So i will not even try to put in one daytrading and portfolio running. If i will do so my productivity will be less. I dont like to work with details and work with numbers. So i will prefer to work with philophy, ideas, macro stuff - all ares where i could fully use my type of thought to get bigger pleasure and better results. So guys, concentrate on your strong sides and work on areas where you can use it fully! Be true with youself about your weak sides! Go for better results!
