We are masters at passing the buck. Why? Because passing the buck is easier than fixing; criticizing others is so much easier than improving ourselves. So instead of solving our problems legitimately (by doing the work required to solve them) we are inclined to blame and criticize while doing precious little else. When we do, our problems, quite predictably, remain unsolved.
Whether you like it or not, you (and only you!) are accountable for your actions. But because you are human, you’ll be sorely tempted to pass the blame. Avoid that temptation at all costs.
