In some ways, creativity like knowledge is a renewable source. If we use it more, we will have it more. Creativity is a quality which each one of us possess in some measure. Though, creativity is present in all of us, to exploit it fully each one of us requires patience and hard work. All of us cannot become Lee Iacoca, Bill Gates or Sabeer Bhatia, but it is within our capacity to be creative in small ways in our day to day life.
Creativity requires persistence.
Putting ideas into reality, giving them concrete shape may not be easy. This is where many creative people withdraw or accept defeat. They start thinking that since their idea is not taking shape, it must be wrong or impractical. They become disappointed and start doubting their creativity. Also there is a human tendency to reject the new ideas as fallacious and impractical.
