I've trimmed those in my life that don't root for me, doesn't matter loudly or quietly. I've deepened relationships that I've had for 10, 20, 30 years by rooting for them, loyally and unabashedly. I've foster new friendships by rooting for them, deservedly or undeservedly. I've realized that it makes my life more fulfilling and it's given me a solid reputation as a side benefit.
