Most of a young lawyer's experience does indeed come from a law firm, and in order to score great law firm opportunities, you really need either great academics or great networking (or both). You do not necessarily need intern or paralegal expertise this early in the game. Instead, I would focus on reaching for an Undergraduate School that really suits you - a place where you can attain excellent academics in subject matters that you enjoy. Join pre-law and really work on technical writing/cognitive task analysis. Towards your 3rd - 4th year in University, then focus on those LSAT scores. Your academics, LSAT score and writing samples will dictate your law school opportunities. A great school leads to terrific opportunities either in-house or at a law firm. Have fun!
