Be Not Afraid of Greatness

"Be not afraid of greatness. Some are born great, some achieve greatness, and some have greatness thrust upon them." -- William Shakespeare

I believe that this quote is relevant and ties in well with my question. You can't choose your parents, the family you're born into, or where you are born. Some people are born into very wealthy, as some may say, successful families, where money is not an issue, and one can have anything he/she desires. On the other hand, there are people born in to poverty, where one does not know how he/she will get his/her next meal or how long one will have to wear the clothes he/she is wearing. Then there are people that are born in the middle. Most people I know are in the upper middle class. We have to work to get where we are, but our parents and family will help us along the way. Since one cannot choose his/her life, there are many different comprehensions of the terms success and happiness.
