Since you're such a natural-born communicator as a Gemini, you have an advantage over other signs.
You're great at using your skills to get ahead in your workplace, through networking groups, or having happy hour with co-workers after your shift.
If you're angling for a promotion or additional job perks, think about showing your higher-ups how you can advance the needs of the company with your skills. Take your casual socializing up a notch to more formal networking.
Perhaps you could take up public speaking, or give presentations to new clients. Whatever the case, you're sure to shine when you're taking the stage!
