This is such an underrated topic. Students miss opportunities not because they're not qualified, but because they simply forget deadlines. I've been there. I've missed scholarships I was perfect for because I forgot the deadline was Friday, not Monday. Here's the system that fixed that.
Most deadline problems aren't about laziness. They're about systems. If you're relying on your memory or a sticky note on your desk, you will miss things. The goal is to build a system that doesn't rely on you remembering anything.
You don't rise to the level of your goals. You fall to the level of your systems.
