The real reason you’re struggling with having nothing new to say.
Content ideas don’t come to you because you’re a creative snowflake who makes it look easy and always gets new or brilliant ideas while taking a shower. Ideas come from who and what you are. Develop that. Become something first before you start worrying about getting ideas for content. You can’t have or generate an opinion if you’re a nobody. You will just have the same opinions that others have told you that you are supposed to have. You will only follow what others have said before you. You will never say or come up with something new. You will just be repeating what others have told you or convinced you is true.
Do not mistake this for being creative or being someone who is good at coming up with or generating ideas. This is just repetition compulsion.
