Positivity is a choice. You can choose to be positive if you want. A lot of people wait for the arrival of their wants and desires before they can be happy. They keep thinking about their problems that they hardly find any time to focus on the solution. The irony of this whole thing is, the more you focus your mental energy on anything, be it negative or positive, the more you attract it to yourself.
The more you speak of your problems, the more they expand. You do not have to wait for things to be the way you want before you embrace positivity. It is your duty to attract the things you want by thinking about them, speaking about them and taking actions to get them.
Always be positive in your thinking, your words and your actions irrespective of what it happening in your life at the moment.
