You can't master something by switching games all the time, by definition. "... switching games all the time..." is the key. What does "all the time" mean? Does it mean not dipping your toe into new waters? Of course not; exploration also deepens your understanding of where you currently are. Does it mean never changing your path? Of course not, but changes in direction should be done mindfully, not at the whim of the current front page of HN (or anywhere, or anybody, else). "Spending a month 'learning' OCaml" is barely divergent from the path you're on. It will affect what you're currently doing, to some degree. A month is (essentially) nothing. In any case, everybody is different. The real question is whether or not you're happy with the direction you're headed.
