To Succeed in Work and Life, Be Mr. T

A T-shaped man has two characteristics. First, he has a depth of knowledge and a focused expertise in one skill or discipline. This characteristic is represented by the vertical stroke of the T. Second, he has an interest in and a willingness to use a broad range of skills and disciplines outside his area of expertise. This characteristic is represented by the horizontal stroke of the T. A T-shaped man is, in short, a jack-of-all-trades, but a master of one.
