I installed a slab front door.
" the gap on the latch side of the door at the top was getting larger" Gap at one side at one end means door or frame is crooked. Possible that door is swelling shrinking. Check that hinges are secure, especially the top one. But since this is seasonal, I suspect a foundation problem. I don't know where you are, guy, but are winters wetter than summers, or maybe the other way round? What kind of foundation do you have? What is the soil type?
Measure twice, cut once.
Look at the nail, not the hammer. Watch the fence, not the blade.
If you hook your thumb over your belt you won't hit it with the hammer or leave it layin on the saw table.
