Virgo, an earth sign ruled by Mercury, is easily the hardest working sign out there. They have an uncanny sense for detail and a methodical approach to everything they undertake, making their work ethic top notch. If you want something done and done right, give it to a Virgo.
Leo, ruled by the Sun, is a fire sign. The Sun never goes retrograde, making Leos a very dependable sign. Like the Sun, they are full of fiery heat and passion. They also tend to be optimistic and look on the bright side of negative situations.
Taureans, people born under the sign of Taurus, can be very slow and seemingly lazy to other signs; this can lead to procrastination. Taurus isn't fond of doing jobs they have no interest in but keeping focused on the fact that swiftly getting through the mundane tasks can leave them with more time for the things Taurus loves to do.
