Pulled this right from the YouTube video. This is my first tab so be gentle.
You can figure out most of the timing and transitions between the different 
parts by watching the video and listening to the song.

(~) = let it ring
(/) = slide

Capo 8th fret
(Relative to Capo)
this is the main picking throughout the song

So damn easy to say that life's so hard
Everybody's got their share of battle scars
As for me I'd like to thank my lucky stars that
I'm alive and well

It'd be easy to add up all the pain
And all the dreams you've sat and watch go up in flames
Dwell on the wreckage as it smolders in the rain
But not me... I'm alive

during the next three lines you do this pattern...

And today you know that's good enough for me
Breathing in and out's a blessing can't you see
Today's the first day of the rest of my life

resume this pattern...

This is supposed to be the bridge before Dave Matthews sings. I tried
to tab it out but I couldn't get it right so I got the first part. 
You can mess around with it on your own.

Stars are dancin' on the water here tonight
It's good for the soul when there's not a soul in sight
This motor's caught its wind and brought me back to life
Now I'm alive and well
