Solving the problems in the world seems to be an impossible task. For any one of us, that is probably true. But I believe that if we each focus on making our own personal "world" better (whether that is ourselves, our family, or our community), the results will spread and maybe the world will start solving it's own problems.
If both of your windshield wipers are the same size you can apply this trick
When you feel like you need new windshield wipers just buy one new one and put it on the driver’s side.
When that one gets worn out, get a new one, put it on the driver’s side, and take the old driver’s side one and put it on the passenger side.
The passenger side one doesn’t need to be as good so your old driver’s side wiper should be fine on the passenger’s side
I look for when my wiper goes on sale and buy one so that I always have an extra one.
Consumer reports says that pretty much every windshield wiper will last about 6 months no matter how good it is. The better ones just do a better job before they get worn out so you don’t have to worry too much about trying to buy high quality to last longer.
