There is one purpose to life and one only: to bear witness to and understand as much as possible of the complexity of the world - its beauty, its mysteries, its riddles. The more you understand, the more you look, the greater is your enjoyment of life and your sense of peace. That's all there is to it. If an activity is not grounded in 'to love' or 'to learn,' it does not have value.
I love readings and my readers, but the din of voices of the audience gives me stage fright, and the din of voices inside whisper that I am a fraud, and that the jig is up. Surely someone will rise up from the audience and say out loud that not only am I not funny and helpful, but I'm annoying, and a phony.
Tradition is but a meteor, which, if it once falls, cannot be rekindled. Memory, once interrupted, is not to be recalled. But written learning is a fixed luminary, which, after the cloud that had hidden it has passed away, is again bright in its proper station. So books are faithful repositories, which may be awhile neglected or forgotten, but when opened again, will again impart instruction.
