A proper club, who will give you training and supervision and carefully guide your initiation.
In Britain there are a number of good university clubs (I learned with ULSA at Leeds) as well as established local clubs like RRCPC, Northern Pennine Club, and Mendip Caving Group. In the US, the National Speleological Society has a network of local 'grottos'. There are established clubs in nearly all countries with good caves.
Also, caving with other enthusiasts is great fun. Outside of tech, the cavers were the closest I've ever found to 'my people'.
