1. Get Yourself an OV Chipkaart
Those of you who were in the Netherlands prior to the dawn of the OV Chipkaart will remember having to travel with a strippenkaart. Thankfully, that is now obsolete. It was one of the most convoluted elements about travelling on public transport in the Netherlands. You needed to know how many transport zones you were travelling through (and then add one, double it, half it and guess which number I first thought of) to pre-stamp the paper strip; that was if your strippenkaart wasn't in at least two pieces because it was long so you had to continually fold it multiple times to get it in your purse/wallet/handbag/pocket and it tended to erode along the creases.
