Clock Time
Source: Internet.
"Do not unwittingly transform clock time into psychological time. For example, if you made a mistake in the past and learn from it now, you are using clock time. On the other hand, if you dwell on it mentally, and self-criticism, remorse, or guilt come up, then you are making the mistake into 'me' and 'mine': You make it part of your sense of self, and it has become psychological time, which is always linked to a false sense of identity. Nonforgiveness necessarily implies a heavy burden of psychological time.
If you set yourself a goal and work toward it, you are using clock time. You are aware of where you want to go, but you honor and give your fullest attention to the step that you are taking at this moment. If you then become excessively focused on the goal, perhaps because you are seeking happiness, fulfillment, or a more complete sense of self in it, the Now is no longer honored. It becomes reduced to a mere stepping stone to the future, with no intrinsic value. Clock time then turns into psychological time. Your life’s journey is no longer an adventure, just an obsessive need to arrive, to attain, to 'make it.'
You no longer see or smell the flowers by the wayside either, nor are you aware of the beauty and the miracle of life that unfolds all around you when you are not present in the Now."
Eckhart Tolle
