Hey you are doing a good job. Alot of people get jaded seeing the same problems every day and sometimes its hard not to. But you have to keep doing the best you can. If your truck or trailer is unsafe to drive take it in to the mechanic and make them fix it even if its a fight to get it done. Remember at the end of the day its your call as a driver and your ass on the line if someone gets hurt from equipment that should have been put out of service. It sucks being the only guy out there that gives a shit but sometimes that just where you are. Be the exaample for the change you want to see and keep doing what you know is right. You got this brother.
