I can't say for sure, but I think newbies like to keep hands that don't really do anything. As a rule of thumb, you should have a rough plan for the first few 2-4 turns with your starting hand.
That said, precons notoriously lack ramp and card draw, so it doesn't surprise me that you were behind for most of the game. But I also do wonder how you shuffled to end up with 16 turns of only lands. Please don't let it be something like the ygo anime shuffle.
