Honestly evaluate what you feed your mind everyday. Every source of input you allow into your mind will become a seed of thought. That is how advertising works. They bombard you with the same ads over and over until you are brain washed into buying their product. Life in general is the same way, filled with sensory input, which when focused on over and over will sway your thoughts which in turn affects your moods. What you choose to pay attention to feeds your mind. If you are feeding it an over abundance of pointless drama (reality TV), negativity (gossip), and meaningless distractions (video games) then the result will be a life of drama, negativity, and meaninglessness.
Be aware that what you watch on TV, what you spend your time talking about, and what types of posts you allow in your Facebook news feed, will have an overall effect on your mental state of mind. If you watch horror TV (too much news, shows with violence) you are filling your mind with images and drama that may come back to haunt you with unhappy trains of thought. If you get involved with gossipy conversations, those drama filled thoughts will be circling around in your head, urging you to share the gossip with others. If your Facebook news feed is filled with people who post negative content on a regular basis, such as complaining about life or other people, this will disturb your peace of mind.
It is easier to regulate what you are feeding your mind, than to eliminate the unhappy or disturbing thoughts once they have been put in there.
You are in control of what you feed your mind. If you want to be happier and enjoy a life of meaning then begin feeding your spirit with more uplifting input. Forget reality TV and come back to your own reality. Take time to see and hear your natural environment. Pay attention to the people in the room with you. Turn off the TV and computer, make plans with people you enjoy being around, laugh until it hurts your cheeks, and make some happy memories. Start on a diet of positivity and you will see amazing results.
So, what's your input?
