in order to enjoy life, it is important to consciously be where you are. if you are at one place at a certain time, but wish you were somewhere else or somewhere in the future or in the past, you are not focused on the moment, you are, in a way, out of sync with reality. and the moment is all you have. if you are happy, you are happy right now. if you are anxious you are anxious right now. you will probably be anxious about something in another place or another time, but now and here is the only reality in which you are aware of anything and where you are anxious. so here and now is where everything happens. would you change anything about your present reality if you could? is it in line with your purpose? or is it your purpose itself that you want to discover? does your life feel like an involuntary inheritance of your environment that you feel is not quite what it should be? even if you would not want to change anything about your present reality, you probably want to grow, to go on discovering the possibilities that life has in store for you. in all these cases it is good to know some more about the 'playground of life' that we're all in.
