Good advice on all these topics exist. If you're serious about greatness, there are patterns you can copy. Just look at the scores of people who are successful at whatever you want to do. Copy them. But none of these patterns resonate. You don't see a pattern and bounce into action. That's the tip-off.
The next time you hear someone say that eating healthy is expensive, ask if they have googled "eat healthy on a budget". There are templates, sometimes even specific to your local supermarket chain. If they say math class at their community college is hard, ask if they've searched YouTube for tutorials. There are dozens of lecture formats, highly reviewed, often by some of the best educators in the world, for free. The right patterns are literally 5 seconds of clear thinking away from them, and they haven't even looked. Because they're full of shit. Can't even be fucked to do basic strategizing about their problems. Obviously, because their problems aren't really problems. Once again, it's a feature, not a bug.
Just having no motivation would be a bug. When it becomes a feature is when people pretend they have motivation but everything is complicated and insoluble. What they really want is for you to accept this narrative. That's why they're complaining to you. They want your buy-in. They want you to agree to treat them as whole, mature, and conscientious adults, while simultaneously remaining lazy, regressive, and ineffectual.
