Does a rich person spend time reading articles explaining how to acquire money? Do NBA players spend time watching tutorials on how to become a great basketball player? Do people in a romantic relationship scour the internet for tips on how to get a boyfriend or girlfriend? No, they don't. Do confident and competent people with a sense of direction need to consume self-help content? Again, the answer is no.
Self-help is geared towards young people who either feel unconfident, confused, stagnant, sad, or purposeless. Unless you want to stay in those low-level phases, your goal should be to reach a point where you feel you no longer need to watch videos or read articles relating to personal development. Being introduced to self-help and learning about new and productive habits are great first steps on the road to becoming the best version of yourself. However, just being very informed about anything means nothing. Implementing and applying what you've learned are the only ways to become successful.
You might feel stagnant or unfulfilled if you've been consuming self-help content for a while and feel like the information has gotten repetitive and unhelpful. Once you've gotten your foot in the door and seen enough content, the ball is in your court. Consuming people's content (including mine) about self-help isn't your permanent or even long-term solution to your struggles. You can lead a horse to water, but you can't make it drink. It's up to you to improve your life.
I'm not saying that you should never consume self-help content after a certain period of time. There's nothing wrong with taking it in it periodically for informational, entertainment, or motivational reasons. You might have a strong sense of admiration for your favorite content creator. Nothing wrong with those things. The point here is that you should eventually be able to consistently have a sense of productiveness, fulfillment, and improvement without needing external sources. When you click on your next self-help article or video, ask yourself: "Why"?
