Not everything has to serve a selfless purpose, but a lot of us go through our day to day serving nobody but ourselves.
How can I make more money?
How can I find a better job that gives me higher status?
How can I buy the car that makes it seem that I’m rich and successful?
How can I,
How can I,
And the list goes on.
How can I help you? is a question that opens up doors (not to be mixed up with, how can I help you so that I can help me).
