1. A 25 year old in a cubical sets your appointments and it's forced dispatch. Sometimes the pickup will be late when you get it... There is no trip planning..
2. You pull over to take a shower you're getting phone calls asking why you're sitting after ten minutes..
3. You argue with anything you'll be threatened with abandonment, and start getting layovers and/or the worst loads
4. OTR is easier than running 2-11 loads a day in city traffic(not just P&D either).. Driving the Midwest and planning 800-2800 mile loads is probably the easiest thing to do in this industry; it's what companies use to have trainees do; You'll be amazed how many people think someone running in Atlanta or the North East every day just can't handle big time OTR
