Andrew Carnegie was an immigrant from Scotland. When he arrived in this country in 1848, he was penniless. His first job was a bobbin boy in a cotton mill making $1.20 per week. By the time he died in 1919, he was one of the wealthiest men in the world.
Someone asked him what he would do if he lost all his wealth. His reply was classic: "If you took away all my money, but left me the people with whom I worked, I could rebuild my empire very quickly."
Carnegie knew that the keys to his success were his compatriots, his partners, his co-laborers. He clearly understood they were the key factors in his success.
Don't try to go it alone. You need people around you who you know you can count on; people you believe in and people who believe in you.
