This a topic I love to talk about. In general, I believe, everybody has her/his own history, knowledge, experience, talents, etc. I personally have many things done unsuccessfully and many others - successfully. When analyzing afterward, it seems that when unsuccessful, this was not my strength. Possibly I was influenced and wrongly excited by something or somebody, that is not for me. Many people love to read how Apple went up, or Microsoft, or Napoleon. But I am an individual, only one of the sort in the world. Others look like me, talk like me, but just partly.
In short, everybody must discover, what is her/his strength and talents and to put much effort to develop. As it is said - success is 1 % talent and 99 % of work. But all 2 parts must be presented.
