I've been having the hardest time closing my matches lately.  I start out strong, put em on the ropes, but more times than not, I can't finish the job & lose my matches.  How have you guys gotten out of slumps like this?  I feel like after I get a comfortable lead, I back off and can never re-gain my footing.
		
		
	 
Here are a few things I did to fix the very same problem.  They worked for me and I am not saing they will work for everyone but it wouldnt hurt to try:
1) Dont keep track of your games and always play one at a time.  I just play until they tell me it is over. If you keep track of games you realize that you are ahead and you slack off.  If you dont keep track of games you never know if your close or not.
2,) Dont ask what the other persons handicap is. If you always assume the other person is either a low handicap and only need a couple games to win or a high handicap and if they get control of the table you may never get it back, it scares you into not allowing them to the table.  
3.) Lie to yourself and convince yourself the other person is a sand bagger and that they are playing way under their handicap.  Even if you dont know thier handicap tell yourself they are a 3 level handicap and they are playing like a 5 this way they only need 2 games to win.  I know this sounds whierd but if you do this you convince yourself that the other person cant get back to the table becasue they already have the advantage of being way under handicaped as it is.  
4.) Set a goal before the match that the end goal isnt just winning. In APA if they get one game I lose a point for the team.  In NAPA if I lose a game they get 3 points. So before the match I set the goal of getting all 3 points in APA and not letting them take any. (20-1 in NAPA)  This way my gooal isnt to win.  If I think I have won then I slack off however if winning isnt my goal then I dont slack off until I reach my goal.   
5.) Lie to yourself.  Pool is 90 percent mental.  If you tell yourself the other person is on the hill and all they need is this one game it will scare you into playing your best becasue you always assume you are loosing or could lose very easy and try your best.  
Like I said, this may not help with others but this is what I did to get over the hump and it works for me.  If I  always play scared I always try harder.  Its when I am not scared that I slack off and it always comes back to bite me on the ass.  Hope this helps and good luck.
