Nothing Can Be Perfect

I'm busy procrastinating. I have my third book ready to send to a pro-editor but I haven't done it yet. I keep thinking I should go through it one more time. Check a few more things. Do another find/replace for repetitive words. Then today I sat down at the local BAM (I miss my Borders everytime I sit in this dive), and flipped through July's The Writer while sipping a low-fat caramel frappe and read some wise words from Janet Evanovich.

The interviewer asked Janet what the most useful thing she'd learned about writing was. Janet answered, "Nothing will ever be perfect."  She went on to explain about letting a book go and move onto the next one.  So I'm taking her advice and moving on to the next one.

Now if only I can decide what the next one is.  Have you ever received some great advice that fit your situation perfectly at the time? Do you have trouble letting go of one and moving on to the next thing?
