However, today's youth have learned that they can do anything they want to do irrespective of talent or ability. You merely have to watch the first few episodes of American Idol to see people embarassing themselves on national TV, because they think that they can sing. Parents have forgot to tell their children along with being able to do anything that you want to do that you also need hard work and God-given talent. Wanting something really bad is not enough to be able to get it always.
The average height of an NBA player is 6'7". However, Earl Boykins, who is only 5'5", plays in the NBA. Earl, as a child, had a desire to play basketball. But a desire is not enough. Not all men who are 5'5" tall that want to play in the NBA will be able to do it, because desire is not enough. You need desire + hard work + God-given talent.
So yes, you can be anything that you want to be. However, it won't happen if you do not have the talent. It also will not happen without hard work on your part. You need to learn to assess your abilities. Just because you want to be a singing sensastion, doesn't mean that you can sing.Common sense says assess your abilities and be real. There is nothing wrong with changing your dream once you learn that you lack the ability to do what you want to do.
