Meditate with a subtle mind

I have found through out my short 28 years of life that getting worked up about things just don't do anyone any good.  I mean sure its hard to just let some things go or to react negatively to others but what is the point of stressing your self out to the point of mental break down about it?  This is something that never needs to happen.  There is nothing that should stress you out that much.  I know there are a lot of people that worry about EVERYTHING!  But there is only so much really that is in your control.  So just let go and STOP WORRYING!  If something went wrong i the past and you are still dwelling on it.  Don't...Its in the past and there is nothing you can do to change it.  Stuff that might happen or you want to happen n the future...again don't worry it has not happened yet so focus on whats happening now and when the time comes you can deal with that issue later.  Meditation can help you get away from the world around you and recenter your self.  Find a nice quite place anywhere does not have to be in your house.  You can get in your car an drive to a park in set in the parking lot just some where where you can just relax and let go.  Close your eyes and take deep breaths in through your nose and out through your mouth.  Clear your mind completely and thing about absolutely nothing.  Let all your worldly problems all the stressors in your life just melt away.  Just focus on the relaxation....now your eyes and feel the refreshness!  Once coming out of meditation your mind will be clear and sharp.  You will now have a subtle mind and can deal with your daily problems with more efficiency.
