Before we call this a character flaw, let's look at what's actually happening. Most people who restart every Monday aren't undisciplined — they're over-ambitious and under-systematic. You're not failing the goal. The goal is failing you. Here's what I want to understand first: when Wednesday comes and you stop — what exactly happens? Is it that life gets in the way, or that motivation disappears, or that the goal just starts to feel pointless? Because the fix is completely different depending on which one it is. And before we design anything new — what does the person you're becoming do differently than the person you are today? Start there. That's the only goal worth building a system around.
