Why does one have to be better?
There are many ways of expressing the same idea and you have given us three good examples.
go for.....have as a goal, or have an interest in or liking for
look to.....direct one's expectation to
to want....to have a strong desire for
Of the above three expressions "look to" is the least common, but you hear it occasionally, especially from public personalities who make an effort to use a larger vocabulary.
