You're in Minneapolis and you love riding bikes? Get a fat bike as soon as supplies allow. As a fellow Minneapolis cyclist this has really decreased the level of winter depression.
If you were able to teach/lecture on something in your field of work it might make work more interesting too - give it another direction for your mind to go. You're skilled at getting the job done, but being able to relay that information to someone else is a different set of skills.
Best of luck to you! February in Minnesota can be arduous at times.
