Get others to do the work for you, but always take the credit: use the wisdom, knowledge, and legwork of other people to further your own cause. Not only will such assistance save you valuable time and energy, it will give you a godlike aura of efficiency and speed. In the end your helpers will be forgotten and you will be remembered. Never do yourself what others can do for you.
Generally speaking, I disagree with this one. I do think that collective accomplishments should be associated with the leader of the group. I also think that if the leader completely usurps the accomplishments of his subordinates, the likelihood of discontent exists. Discontent leads to mutiny. Mutiny results in a power struggle. I’ve been at both ends of the spectrum and I believe that there is a careful balance that must exist in order to sustain upward mobility, downward contentment, and holistic productivity.
