Use systems to get where you’re going, not goals:
My problem with goals is that they are limiting. Granted, if you focus on one particular goal, your odds of achieving it are better than if you have no goal. But you also miss out on opportunities that might have been far better than your goal. Systems, however, simply move you from a game with low odds to a game with better odds. With a system you are less likely to miss one opportunity because you were too focused on another. With a system, you are always scanning for any opportunity.
Applies to personal life, biz, programming, hobby, whatever. Use goals to figure out what systems you need in place, then get habits and systems going to make those goals, or something better, happen.
Yet another way you can use your skills as a developer to construct a system that really solves the problem, and not a symptom of the problem!
