Your sign of Virgo, as an Earth Sign, knows the value of hard work. You're not afraid to jump into a task and get your hands dirty, as long as you can trust that you're being paid fairly. You believe that this gives you character, and you're right!
Try not to compare your work ethic to that of others, though. You may work twice as hard as anyone in your company. But no one likes being called out as a slacker. Let karma correct the shortcoming of others, and use your skills to advance to the level that suits you.
