We measure time: seconds; hours; days. We even have a name for what's been and what is about to be: past, present, future. We even think about the quality of time: whether something is a "waste of time", or whether something is worth the time. But, what is time really but an experience?
The past, to me at least, is like a dream. The future is merely a potential. It is the present that exists now. It is the present that I want to learn to embrace.
"Do not dwell in the past, do not dream of the future, concentrate the mind on the present moment". Buddha
