“The less you associate with some people, the more your life will improve.
Any time you tolerate mediocrity in others, it increases your mediocrity. An
important attribute in successful people is their impatience with negative
thinking and negative acting people. As you grow, your associates will
change. Some of your friends will not want you to go on. They will want you
to stay where they are. Friends that don’t help you climb will want you to
crawl. Your friends will stretch your vision or choke your dream. Those that
don’t increase you will eventually decrease you.
