Answer: Three Keys to a happy life Everyone wants to live a happy life. But where does happiness come from? Buddha said "Life is a creation of the mind." Shakespeare put it this way when he said "There is nothing good or bad, but thinking makes it so." Therefore, the first key or the most important key to a happy life I would say is Positive Thinking.
Maybe all of us have heard of this famous question: is the glass half-full or half-empty? An optimist observes what is in the glass – the full half, because he focuses on what he has. On the other hand, a pessimist observes what is not in the glass – the half empty because he focuses on what he doesn’t have. When we always think of what we don’t have and what we are losing, we never feel happy. Furthermore, negative thinking can take a lot of time and too much emotional energy, which absolutely does not lead to a happy life.
In addition, positive thinking makes us have a feeling of excitement about something pleasant or exciting that we know is going to happen. Such a feeling is anticipation. No matter what our circumstances are, if we have something to look forward to, we bring happiness into our life well before the event actually takes place. In fact, sometimes the happiness of anticipation is greater than the happiness of the actual experience itself. With this in mind, we may say if the future holds no pleasant promise - it's very hard to be happy.
I hope this helps you.
