This blog post will not have all of the answers to this question. I will not sit here and pretend that everything I write in this blog will immediately turn you from negative to positive. But what I can promise you is that you will find it in yourself to push forward. At the very least, you might see a different perspective on what exactly is negative and what is positive. You may even find that what you thought was positive is in fact negative, and vice versa. What I can tell you is that there are things I will be writing that you will have definitely experienced at some point.
The first thing you can do before you can start to work on your negativity is to try and analyse why you are negative. Now, not everyone is going to be able to find the reason they feel negative at times. The truth is it will be difficult to find the route or source of that anger or disappointment. Finding why you are negative to begin with is a journey that will take you a while to figure out, and even then, not everyone will be able to acknowledge the exact reasons as to why they feel that way.
But, once you are able to find the reasons as to why you are so negative, you can begin to look at the root of the issue. What can you do to change the thing you feel so negative about? What is the source of that negativity and what is the source of what is wrong to begin with? Is it changeable, and if it is how can you change it? If it is not negative, then what can you do to alleviate it until you are able to cut it off completely?
