Musicfan123,
In NYC I would go to the artifical waterfall on 53rd St. between Madison & Lexington (I believe), or I would sit and stare at the rock outside the Sony building. When they ran the water underneath, and if you concentrate on the water flowing, there comes a time when the rock starts to move visually. Then one could see the water AND the rock. And after awhile the water would stop moving.
To make the water stop, watch one drop of water falling from the top of the waterfall and follow it all the way down. when it fits the ground, go back up toi the top and repeat. when you get tired, or you find your thoughts still intruding, follow 2 drops all the way down. since they are not at the same elevation, you have to concentrate on both of them fallin, one usually lower than another. after another 5 minutes, try to see 4, then whole streams. there should come a time about an hour later where the whole water fall seems to stop. then you can either get scared and it will start to move, or you will see how long it can stay stopped, or how long you can go without thinking and making it move again. your first thought will of course be, "It stopped moving!".
And of course there are the parks, although most are too noisey, the Central Park Zoo is always welcomed, especially during snow storms. I always tried to go whenever it snowed. The monkees go absolutley nuts, the polar bear is in heaven and the birds go out of their minds.
The one place where you can hear your thoughts the loudest are in churches, because it is usually so quiet. Man, try NOT to think about work, or your problems in a church. The hardest part is sitting absolutely still without blinking, fidgetting, moving around, craning your head, not going to sleep, but not having thoughts being put into your mind by any religious icons.
And for sleep - the absolutely best place to sleep is at the Museum of Natural History Planetarium. Just lean back, look at the stars and zzzzzzz. The older you get the faster you fall asleep.
I wonder if the cops have started giving tickets for people sitting on park benches yet...
Are there any sensory deprivation tanks for rental in your area? They usually start at $25 per hour. Get in one of those and see if you can't hear yourself thinking. BTW, that's a good tip for someone if they want to start their own business.
Otherwise, get a weekly massage. You'd be surprised how long a full body massage will last. it will relax you all over, give you a new look on life, and boost your confidence and efficency levels. It's the best way to reduce stress. You'll be a NEW man for about 2 weeks. repeat as necessary.
