Hopefully you were able to spot the relationships in your life that are not so good for you. It is not an easy thing to do, and by no means are the answers simple. However, if you begin by recognizing the people who bring you down, you have made the first critical step.
With the bad, there is always the good. Seek out the people who make you feel like you have the world by the tail. You know the ones I'm talking about, the people who as soon as you greet them, you feel great! In the past as I have eliminated the negative energy in my life, the positive people have come in droves. Some of them are my life long friends, and others are the strangers I encounter in my everyday life. I make it a point to only surround myself with people I want to be like, people who are happy, productive, and really living.
Right this very minute, think of someone good in your life and contact them. Call them on the phone, send an e-mail, or even go see them personally. See what happens when you put your attention on these relationships. I bet you will be pleased!
