People are always wanting to put earthly limits on the size of the universe. They confuse the boundaries of earth with the boundaries of space. And, quite honestly, I don't believe that there's any boundaries to space. It's space, for God's sake. Why limit something that needs no limits?
Everything we do or say is influenced by our personal agendas. Even when we're completely devoted to the good of other beings, we still think about how it will influence us. In the end, we may be doing it for the other person, but it's impossible to at least THINK about how it will change your life, or how it will make you money, or how it will benefit you. And it's even gotten to the point that volunteers are being paid.
