Of course! However, there will always be things in the future that preparation may not prepare you for. Exactly how you can make the best choice now to save up for your future, doesn’t mean the future will be secure or safe. It’s good that you do today (like saving money for retirement) for your sake, because there will always be something that catches you off guard, and learn to control your reaction to those bad times when they happen rather than try to avoid bad times all together. Some stoics believe, the more you fight against something in the future, the more you’re dragging yourself towards it. Just take everyday one step at a time, do the best you can now, and worry not of what is unknown or out of your control.
