Stupid things you can do to ruin a nights work. A must read for anyone who is totally confused about which type of scope to consider.

Nothing is as easy as it looks.
Everything takes longer than you think. Anything that can go wrong will go wrong. If there is a possibility of several things going wrong, the one that will cause the most damage will be the one to go wrong. If there is a worse time for something to go wrong, it will happen then. If anything simply cannot go wrong, it will anyway.
