God gives us some choice in the friends we make, and this is fortunate, because we can then alter the environment which influences us. If your aim is the stock market, you can choose friends who’ll be helpful in getting you an advisor or a job on Wall Street. You can also choose friends who’ll help you grow into a great human being.
Of course there are limitations—you don’t choose your parents, your elementary and high school, your country, your neighborhood. These are gifts. Appreciate them.
We accrue much from our teachers and chance meetings too. Listen to what the still, small voice within you says. Make the most of it.
