Good advice has to be specific. Sure, a nice saying can work really well if it happens to fit your situation but it's rare that generic advice captures all your needs. Yet it's easy to fall for. And super easy to produce.
It's common among indie creators to follow generic advice to grow their products. Understandable when it's a skill set you're unfamiliar with like marketing. I've done it before too. The countless listicles detailing the 10 things that will make your product a hit. Content marketing, cold emails, featured on Product Hunt. But so often these tactics aren't suited to the products creators are building.
The same can be said for the latest trend of cold-emailing/DMing to promote your product on Product Hunt. Someone once shared this generic advice that this tactic works and now so many are blindly following it without any thought about how it fits their product.
The hard truth is, that learning new skillsets is difficult and time-consuming. There are no guaranteed ways to be successful. No shortcuts that will work 100% of the time. You need to learn a lot and adapt the generic advice to your specific circumstances. And it's likely you still won't be successful. But you would've improved at a skillset that can be useful for your next product.
The next time someone gives you some generic advice, think twice.
