I just do not hang around anybody that I don't want to be with. Period. For me, that's been a blessing, and I can stay positive. I hang around people who are happy, who are growing, who want to learn, who don't mind saying sorry or thank you... and [are] having a fun time.
Success tastes that much sweeter when you have people to share it with.
Our job as humans is to hold on to the thoughts of what we want, make it absolutely clear in our minds what we want, and from that we start to invoke one of the greatest laws in the Universe, and that's the law of attraction. You become what you think about most, but you also attract what you think about most.
