"Your subconscious listens to how you talk to yourself. It listens to your wants, needs, and goals. It tries to make these a reality, in the background influencing your every decision.
If you talk positive about yourself and your goals, your subconscious will try to make that happen.
If you talk negative about yourself and your goals, your subconscious will try to make that happen.
tldr: stop talking/thinking negatively about yourself"
If THAT'S what you took from that, your inner criminal is showing.
Aren't you just an angry South Pole Elf??
