I'm in IT. It's the advice I wish I'd followed from the beginning.
Once you get comfortable in your job and it becomes routine, you need to find a new one. Keep growing your skill set, and probably take a hefty raise each time.
Don't worry about being a job hopper - it resolves itself easily enough when you don't find the next position for a while.
It's probably wiser if you climb on the 23 year old's shoulders instead. They don't need ibuprofen for back pain yet
