Stress
For glaziers, stress is likely to be a seasonal thing. If you work in an area where very little construction takes place in the winter months, then you'll have time to decompress.
Get some extra sleep, read a bestseller, and tackle all those chores around the house you've been meaning to get to. Although, as winter wears on and you get more restless, you'll catch yourself thinking "is it spring yet?" over and over.
The flip side of that is your warm weather schedule is likely to be incredibly busy. If rain delays a project, then the rest of your schedule tumbles like a house a cards. Chill. Winter is just around the corner, and down the road, and over the hill a bit. You'll make it.
