What was the best piece of advice you ever got? who gave it to you? when did you get it? did you use it for a good affect? ?

Is this a question for an essay?

You have to answer on your own example, but for me, it's like this:

The best piece of advice I ever got was from an older friend who was advising me in my college choice back when I was applying for my college.

She said that upon choosing college I can't possibly have all the information about the colleges I consider, so I will end up guessing anyway. In this case it's better to worry less about the college choice and to try to make the best out of the experience once I am at the college already. This advice helped me use the time at my college more effectively.
