yesterday i attended a promotion conference of 'mobile internet', as newly member, my collegues and i were asked to record and make a review. what i admired most is not the product itself, because actually i don't know exactly about it. it's the teacher, who can build his lecture in a clear structure and lead us to the centre point of the conference. i found that if you want to convince somebody, you need to make them consider sth as the way you do, or if you can analynise the situation from their aspect(or at least make them feel you are at their point), you may succeed as you want.
