I bought a Ferrari...and then sold it after a couple of months.

I am sure that there are many Christians who will confess that their experience has been very much like my own-that we had long known the Lord without realizing that meekness and lowliness of heart should be the distinguishing feature of the disciple, as they were of the Master. Such humility is not a thing that will come on its own. It must be made the object of special desire, prayer, faith and practice.

Well, my mum's been a tennis coach - she coached me till I was 12.

The coming revival must begin with a great revival of prayer. It is in the closet, with the door shut, that the sound of abundance of rain will first be heard. An increase of secret prayer with ministers will be the sure harbinger of blessing.

I had to pay an incredible amount to get insured on it and, after a couple of weeks of driving it around, I realised it wasn't quite my style. I'm not flash by any means but a bright red Ferrari is a definite head-turner and I hated that. It was also incredibly impractical, particularly when it came to finding space for a friend or for my tennis bag, so I decided to sell it after a few months.

I decided at the outset to invest in a fairly broad range of businesses, as I didn't want to get pigeonholed into one sector.

This will be my first Grand Slam final without Roger Federer or Novak Djokovic on the other side of the net, but I don't think being the more experienced player will make much difference to my approach.
