Always root for the person you want to win and never against the person they’re playing!
When you see one person receiving preferential treatment… don’t seek to have that treatment taken away from them but seek to have that treatment spread out more liberally among yourself and others. A lot of people come in a very childish or selfish manner complain when they see someone else being treated better. The only depth of mind and spirit taking accomplishes that of having the other person reduced to their own level rather than seeking to have they themselves raised up to that level they are witnessing.
