This isn't something that develops over night. You need to have experienced at least one lucid dream in order to have the self-efficacy (belief in your ability) to have further lucid dreams. You need to have had success in order to develop the mindset of being a lucid dreamer, and each lucid dream confirms that mindset.
But look, according to your profile you have 25 lucid dreams, and you've been at it since last February. Some people can go years of trying, only to have one measly semi-lucid that they immediately awaken from because they never developed the capacity to lucid dream.
That's why this tutorial basically aims to bypass the tortuous process of becoming a 'natural' bit-by-bit, through experience, by instructing you to act like, and
believe, you are a pro already, it's that intent that will get you your initial lucid dreams. From there, belief is second nature.
This is a bit of a shameless plug, but I wrote a thread outlining my ideas on intent in more detail, you may find it useful, maybe not:
