Remember, what Youtubers show on the internet is not always going to reflect spiritual enlightenment on their behalf. To those that truly are successful, you have to analyze how they might've grown up, the societal class they were raised in and consider any natural spiritual ability they may have.. most Youtubers don't consider these things.
They might think they found the secrets of "unlocking your potential," and tell people it's really easy and quick to do. The fact of the matter can be most Youtubers simply were lucky and maybe had favorable Natal Charts to succeed in Youtube, and again, not necessarily a reflection of spiritual enlightenment.
Take time to analyze your own weaknesses and strengths, and understand that your manifestations or goals can be both easy and hard to achieve. It really is going to depend on your own strength, the technique and timing of your work, and the difficulty of your goal.
Read back on the sermon above and the JOS articles below, I hope this helps.
