Here is my 1st tab ever. It is completely by ear. Please rate it and tell me any 
corrections where ever necessary.

Key: Am

[Intro]
For the intro you can either play Am-F-Am-E chord progression with one strum or 
play Am-F-Am-E traid progression

[Verse 1]

Am				      F
Life should be like a game of cards
               Am
You make a mistake
Em
Shuffle the deck and start over
Am					F
It should be just like drivin in your car
                    Am
Get lost and your navigation system
                  Em
Gets you closer

[Bridge]
      Am
But there ain't no handbook
F
You're on your own
Am
Got no instructions
Em
When it comes to love
Am
Cuz once you do something
F
Can't be undone
Am
Wish I could take back
Em
Letting you go

[Chorus]
                 Am
If I knew then
	          F
What I know now
		     Am
I wouldn't have said
			Em
I don't need you around
		Am
Alone in this mess


		 F
Silence is so loud
			       Am
So I would treat you the best
        Em
Baby if I knew then
Am					F	
What I know now (What I know now)
Am				         Em	
What I know now (What I know now)
Am					F	
What I know now (What I know now)
                       Am
Yeah I would treat you the best
        Em
Baby if I knew then
		(stop strumming and immediately palm mute the moment they say now)
What I know now

[Verse 2]

Am			   F
Wish I get remote controls
		Am
Then I just rewind into
		     Em(alternatively, you can palm mute after playin Am and not play Em atall)
The time it was better
	    Am
It should have a restart button
F			     Am
So, I could travel right back
			Em(mute out immediately after one strum at her)
To the day that I met her

[Bridge]

[Chorus]

[Chorus x2]
