Clinging to a dead end job is a mistake. Instead of staying in a stagnant situation, look for a new position. You're much more capable than you realise. Moving into a rapidly growing field will pay off handsomely. Instead of being content with assignments that are beneath your ability, you can finally land a position that challenges your intellect and excites your imagination. Take control of your destiny. Stop listening to people who undervalue your skills and experience.
