Use the skills you have now to add as much value as you can now

Don't get bogged down doing a bunch of boring repetitive stuff now unless it is required. Follow the Pareto Principle http://en.wikipedia.org/wiki/Pareto_principle and knock out the big stuff. Demonstrate as much value as you can. Solve the problems you know how to but don't solve them throughout the whole system just yet. You can do that later. Yes, you'll develop a backlog of little stuff that has to be fixed; the time will later come when that is urgent.
