a couple good practical lessons are:
Drink 32-64 ounces of water, in a short period of time (half hour). Then see just how long you can CONTROL your own bladder.
Go stand at the ocean shore and WILL the tide to come in upon your command.
Look up at the sun at high noon and command it to set NOW.
Stay in bed ALL day and notice what happens with the rest of the world - earth still manages to spin on it's axis, traffic lights work, commerce goes on, LIFE goes on - without your express permission to do so.
Examine your own life and where you are RIGHT NOW and ask honestly if you've really done such a bang up job of orchestrating everything.
any of the above should have a HUMBLING effect. which is exactly what our EGOS need. we may want what we want when we want it, but to echo another post, that is just our Self Will Run Riot. Our agenda isn't to actually bring about order and calm, we are instead seeking just another "excuse" when things don't go OUR WAY to pout and fuss and drink at it.
