If you don't brainwash yourself, you will be brainwashed. That's because the subconscious mind does not remain idle. It's constantly picking up information and intel from elsewhere.
So, if you aren't consciously giving yourself commands of greatness, speaking well over yourself, telling yourself you are what you want to be, you're giving your power away.
By talking to yourself, you are directing your creative forces. You are directing your raw creative power.
It's better that you give the commands rather than social media or the news.
Take your power back and say, "Today is a magnificent day. I feel magnificent. Wonderful things are coming to me today. I feel strong. I feel energetic. I feel happy. Great things are happening"
You are now commanding the energies around you, and they will take heed.
