Even those who don't have any comfort zone still find it difficult leaving their poverty and lack stricken environment for the fear of leaving their perceived friends and relatives. I've come to realize that anything we do in life with fear in mind doesn't flourish. Fear is a weapon, a negative weapon at that.

Anyone who's ever afraid of failure will always depend on what opinion people have of them to form their decision. If we've to count anyone who ever invented anything we will find out that they didn't win at their first attempt. There must have been series of failures before they succeeded.

Those into Ponzi schemes will understand  this better.
