Thin line

There is a thin line between between confidence and arrogance.
A thin line between crazy and genius.
A thin line between believing in your ideas and being stubborn.
A thin line between love and obsession.
A thin line between a discussion and an argument.

A lot of the times you believe you are on one side when actually on the other. A lot of times people will tell you, you are on the wrong side when you are on the right. I think you just believe that you are on the right side and work towards what you want. There may be times when you may want to check whether you are on the right path but continuous examination only leads to analysis paralysis.
