There is a good time for voice mail...

You ever struggle with the past.  Think about it, if it is the past there is nothing new to be collected let it pass through your mind like a bad song.  What do you do when you see one of those people that drain your energy out of you calling on the caller ID?  You ignore the call and let it go to voice mail.  You can do the same thing with the past in most cases.  When your ready to deal with the information listen or just delete it if you chose. 
If your working on your attitude you have a choice on what you allow in your mind.  Just remember your brain is like a computer;

Junk in, Junk out...

Make it a great day, it is your choice!
