This was me last couple of years. I don’t feel it atm as I’m new to my jobs and I certainly think getting out of my house for work helps make it less monotonous, but I can see it happening again on the horizon.

Its an useful feeling, it prompts change and makes us into more interesting people with more to offer the world. What’s really helped in the past has been having a meaningful goal to work towards (savings being an obvious one), and in better times, scheduling in something unusual or out of the ordinary when I can (an overnight trip somewhere new, trying out a new activity, even looking at and applying for new jobs). I may not necessarily enjoy the latter, but it does provide enough contrast/discomfort to help me regain appreciation for my life or remember why I originally chose to play certain things safe.
