Just get out and do something.

'Socrates himself is particularly missed. lovely little thinker but a bugger when he's pissed'
Was the venerable proponent of the examined life and the advantage of knowing ones self prone to bouts of drunken introspection? We will never know but can there ever have been an age more fond of self analysis than our own, and are any of us any the better for it? It would be naive to dismiss  out of hand the urge to somehow get to the bottom of our problems by trying to understand the inner workings of our individual psyche but seems to me that it's important to hold on to two cardinal truths. First, not everything is our fault. Many of the problems that beset us are social problems and quite beyond our individual control. At the same time we are all the result of the dynamic between nature and nurture - we are the hand that was dealt us. We can do little but play that hand as best we can.
Looking inward may have a part in salving a persons unhappiness but surely it is better to turn outward. Take up a physical or creative challenge. Hard physical exercise, getting out in the fresh air and getting a bit of sun on your back, just soaking up the wonder of the natural world. These simple therapies can be worth more than all the supposed insights gained from hours of naval gazing.
