From my readings of the Wiki and the OSM forums, I get the idea of the general method that most users follow in editing the map is to start with the biggest connective feature of any map - the roads. Just ensuring that each road has the correct positioning and shape is intense work. But it is vital work as these roads literally represent the "veins" of the map. All other features flow from these veins.
I plan on following that method - that is, focusing on the roadways before the I move onto the next major feature, the buildings. With that said, I am not going to follow that to the letter. I work as an auditor in my regular job. One of the keys to that line of work is a meticulous attention to detail - I need to be observant and very focused on the work at hand. I have found over my years doing this job that one of the tricks to staving off boredom or the related feeling of tedium is to switch it off for a different type of the same. Basically, I find it beneficial to "break" the tedium by changing it up for a short period. It recharges my batteries and allows me to launch into more without getting cross-eyed. I will do the same for my mapping work - switching to a few buildings here and there to stop myself from abandoning the effort.
I am also pretty new to this process so I'll probably start trying out some of the other mapping features over time. Makes the process even more interesting to the fledgling mapper.
