I READ IN A BOOK

This is something about business taught in a class room by a professor.

Students grasped this quickly. No student will have a doubt. No wonder

A professor explained his students about succeeding in a BUSINESS as

If you see a pretty girl in a party and yourself proposed her for you to her means DIRECT MARKETING.

If your friend talked to her for you, it is ADVERTISING

If you got her telephone/mobile number and you talked to her next day is TELE MARKETING

If she herself proposed to you is SUCCESSFUL MARKETING

When you proposed to her and she slaps you, it is CUSTOMER FEEDBACK

If your friend also proposed to her and got slap, is BUSINESS COMPETITION

I wanted to add some more thing.

If you propose more than one girl, then it is MULTILEVEL MARKETING.

If you touch her hand and she smiles, then it is ADSENSE or PAY PER CLICK PROGRAMS.

If a marriage broker informs you about her - is AFFILIATE.
