When one searches on the internet (through Google, Bing, or any other search engine), one often comes across MLM minded articles, and so many of them are touting "no negativity". In fact, heaps of articles are online about how to deal with negativity. Some may even quote 'studies' that claimed successful people avoid negative people. Some of the articles are actually relatively accurate, but many of them are just outrageously wrong.
One website used this definition:
Negative people are friends, family, strangers, associates, or prospects that talk badly, or in a non-positive way about your dreams, goals and how you plan on accomplishing them.Why would people be positive about your dreams, goals, or potential accomplishments? Your friends and family will probably support you just because they know you. But why should ANYONE ELSE care? It would be up to you to convince them.
The same author went on to describe techniques on how to overcome the resistance of the prospect... Though prospect here means a potential recruit into the organization, not a prospect for a sale. But that's not the problem.
Another author claimed that negativity comes from lazy people who can't profit easily from MLM and create a rant blog about it, then went on to use "pyramid // pyramid scheme" obfuscation to deflect the criticism. It was a classic diversionary tactic.
Both suffer from a fundamental problem of lumping in all criticism, including skepticism, as "negativity".
And if you can't tell legitimate questions from insults, you can never improve your situation.
