People now a day are only thinking within their consicous limit, in other words, they are narrow minded.
Secondly, I did a self study, a BAD point about a thing require about 4-5 GOOD point in order to "neutralise it", so 2 bad point about a thing need 8-10 good point about it, why? Because everyone in this world expect everything to be perfect, whats the point of that, nothing in this world is perfect.
Thirdly, you can't run before you know how to walk, you can't ride a bike without falling over or have someone help you, they expect to use the system perfectly like Pro in the first time and can't take failure. The more you expect, the more you disappoint, so why expect anything at the start, learn as if a baby would, a baby won't give up how to walk if he fall on the gound so many times, no one in the world should either.
