It is important that we a careful about what we give our focus to. In my life there have been times where I focused on negative things so much. Most of the things that I focused on I had no power over and this caused me to become unhappy. More recently I have made a commitment to focus on things that are more positive and sharing a more inspiring story with the world.
Sometimes people focus on negativity just to focus on negativity without really wanting to change things. Simply focusing on negative things does not solve problems.
You will find that people who focus on negative things do so because they are unhappy and the negative things that they focus on maintains their unhappiness. I was the same way in the past. Early on in my life I had been conditioned to expect negativity. Therefore, I began to anticipate negativity. I anticipated negativity which was based upon my own expectation.
It is important that you are clear about what you focus in on day by day. This means that types of people in your space. The types of videos you watch on youtube. The types of music that you listen to. Focus on the positive and you will find happiness.
Happiness is a choice and the choice is yours.
