Sir Paul McCartney has found one positive amid the turmoil of his divorce with estranged wife Heather Mills - he has learned the gift of "patience".
The 65-year-old has been embroiled in bitter divorce negotiations with the ex-model, who launched a string of scathing attacks on the former Beatle last month (Nov07), and is now facing a custody battle over daughter Beatrice.
When asked what 2007 has taught him, he admits, "F**k all (nothing). Algebra? B Minor? Patience, perhaps? Obviously the low point was the whole divorce thing. That situation isn't madly great. But there you go. Patience is required. It's happening and I'm working through the process.
But the former Beatle insists the year's hardships have resulted in an outpouring of optimistic music:
"I tend to do hopeful songs in order to counteract the angst. I'm not so good at angst-ridden songs. My natural optimism tends to take over."
Mills and MCCartney have been separated since May 2006 and have a four-year-old daughter, Beatrice, together.
