Feed your mind consciously. It is very important to be conscious about what you are feeding your mind because your mind is like your storage house. It stores whatever you feed it and releases it back to you.
It is important to note that your life is shaped by the things you feed your mind. Just like your choice of food affect your body, your choice of food for the mind affect your destiny. If you do not carefully select the things you feed your mind, you will end up destroying yourself.
Whatever you do not want in your life, do not feed your mind. You are not supposed to watch, read or hear everything. Be actively conscious about the things you allow to penetrate your mind.
