Promise of financial freedom

Please bear with me if you have been successful in below.
Point one, positive thinking does not work. I have come to notice that
failing sales department use the motivation or posisitive thinking talk
in order to appear genuine. That's what we call cop out in marketing. They do so
because they are scared to death that their department might fail. You see in sales position adverts,they say 'positive thinking'. Bollocks! That's their strategy of hiding their insecurity.
Any successful organisation would not question your state of mind if they believe in their services. Strong people could never be demotivated by someone's negativity. Most of them offer commission based only salary while stating the earning potential as limitless or up to so much amount. Yes, it's limitless because you'll hardly make money.
They only tell you about their commission structure once you are there. Why? Because they know their structure is shit.These organisations are run on con artists principle. They are a group of dedicated individuals in drive to increase they pocket share.I would never work for a commission only job. I still love my sales career but there should be a compensation of some sort that anyone could use as a benchmark for working extra hard thus I earn a commission. Those organisations hardly admit making mistakes. They either blame their employees' incompetence.
It's time I put this into perspective next time I go for an interview.
