It's interesting to note the "nodes" of slang: there are lots of slang words for money, for sex, for everyday activities. The aspects of life around which we revolve constantly, and which is a very important aspect of any language.

Keep starting, and leave the finishing to the forces which you don't understand. Serendipitiy is powerful, accidents will happen, and the more you start, the more opportunity, the more room there is for these events "out of your control" to happen. It takes so much weight off of me to think in this way. My job is to start, and to make sure my environment makes learning/working as convenient as possible. But there is much beyond that that is out of my control, and for good reason. If everything I wanted to accomplish were left up to me alone, not much would get done. Sabe?
