For some it can be, it all depends at what stage your at in your business.
For me, it isn't but it has an opportunity to be as I build a new round In a complete new area which I'm not familiar with for instance.
But ones just starting out, organising and building their rounds, ones who don't work in the rain when it comes to days off work or bad winters etc etc. Just because some feel they have it easy, it would be wrong to assume that others don't find running and operating their own business a stressful thing.
It's just being mindful that's all, as not all things can be covered by sweeping statements
