I have researched on different things in my life i a a banker daily i deal with thousands of people i always had conversation with different type of people and i have got different results from different people!
If you want help some thousand people you will get help from now one and if you want and idea from some one you will get free ideas from many people which will be worth less only will drag you toward the failure side!
I have seen in my any people nature that when you want to talk to them for something very important they will say they have no free time for your work.
For Example:
If you say a student that go and do some work for you or go to market and bring something so he will not listen to you and he will reply to you that he is not free he need to study but the same student will waste so much of the time with video games laptop Movies !
