My training has been on and off due to a couple of injuries (rugby) and an influx of other things having to be done yesterday but since doing squats and deadlifts I've seen improvement in a few places.
At work I hurt my right shoulder twice, the second time when I lifted one of the tools in it's case onto the truck with one hand (it only had one handle). They changed it to 2 handles and labelled it "26kg. two person lift." Now when I get told not to pick it up by myself I say "If I can deadlift 120kg, I can pick this up" Although 120kg isn't much, it's made things easier. The physio basically told me to get stronger to prevent the injury happening again.
When playing rugby my squats have helped me get lower in tackles and scrums, and counter rucking is so much more fun I catch myself laughing occasionally as I push through. Also a general increase in strength has been helpful when relieving the opposition of the ball after a tackle.
It also makes me a better dad because my son watches and wants to join in. Whenever we're in the shed he picks up his little barbell for some military presses or puts on my boxing gloves and says "I'm doing exercise daddy" as he punches the bag.
