I totally agree with you. Sometimes in life there comes a point where you think that you don't have anything or in particular that which your this friend or that person has and you believe you can't do it or have it which is a totally wrong approach.
Imagine if they had thought the same about everything then it would not have been possible to achieve that which they have right now.

Once a millionaire said to me

People are not interested in copy cats and losers. You want to see you, what unique can you have and show to them. Addition to that you have to be different from others if you really want to do something great and crazy.

So now all the time I keep in my mind and try to improve myself with each and every day.
