According to my own experience, the highest level of inner calm comes from the development of love and compassion. The more concerned we are with the happiness of others, the more we increase our own well-being. Friendliness and warmth towards others allow us to relax and help us to dispel any sense of fear or insecurity so we can overcome whatever obstacles we face.
Writing is total grunt work. A lot of people think it's all about sitting and waiting for the muse. I don't buy that. It's a job. There are days when I really want to write, days when I don't. Every day I sit down and write.
