I think that you may have misunderstood the point that I was trying to make. I am not advocating excessive caution. Rather, I value self-knowledge and knowledge of the environment and the people you interact with in that environment. Obviously, a certain amount of margin of error should be included in any decision making.
It has been my experience as a driving instructor that most pupils are entirely too cautious especially on faster roads where going too slowly may cause a following vehicle to attempt an unsafe overtaking manoeuvre
Always drive within your competence, at a speed which is appropriate to the circumstances so that you can stop safely in the distance that you can see to be clear.
In driving, as in life.
First-time poster, long time lurker. This discussion piqued my interest.
If you have your own business, a very cost effective way of promoting it is to get a part-time job, (or 'side quest' in D&D parlance) that involves delivering something such as catalogues, phone-books or even takeaway food or a paper-round in the location where your business operates. You can easily slip in your own flyers or business cards in along with whatever you are delivering. The wage from the part-time job will easily pay for the extra printing and mileage costs. I do this and my p/t employer hasn't found out yet or even explicitly or implicitly forbidden me from doing this; in fact, my p/t boss is pretty wily entrepreneurial sort of chap so he would probably actually approve so long as I am still good at his job.
