You're a creature of habit. You strive for security. Concrete goals are your friends. Your pace is steady, and you refuse to be rushed.
But know that a plodding pace can drive others crazy. Those routines could turn into ruts if you aren't careful. And there's a reason why "bull-headed" is another term for stubborn!
Tenacity is one thing, but make sure you aren't so set in your ways that you can't change no matter the circumstances.
Don't be afraid to stretch and try something different at work. You might discover a new skill, and you'll certainly score points with the higher-ups!
