I would start with the part of language that interests you most. I'm a grammar nut, so I started with the sorts of grammatical structures in my language, Shabkiuza. Others like phonology and phonotactics, so they concentrate on the sounds of the language.

It also depends on what your language is for. Are you creating an International Auxiliary Language, something like Esperanto? Is it a philosophical exercise, something to explore the way that human thought is influenced by language, or vice versa? Or is it an artistic languague, beautiful for its own sake? Perhaps it is associated with some story you have written, or would like to write?

There are no rules, and anyone who tells you that there are is telling you their rules, not yours. The most important thing is to enjoy it.
