I like to think I have a good few years left of my career yet, as long as I stay fit and healthy. However, it's always good to have a backup plan, which is why I have been working hard to build my business portfolio outside tennis.

Owning a property is great as that's my base and the centre of my family life.

Shut the world out, withdraw from all worldly thoughts and occupations, and shut yourself in alone with God, to pray to Him in secret. Let this be your chief object in prayer, to realize the presence of your heavenly Father.

As soon as I walk through the door and see my family and the dogs, I feel relaxed.

Obviously you try to keep as much of your private life as private as you can.

The enemy uses all his power to lead the Christian, and above all the minister, to neglect prayer. He knows that however admirable the sermon may be, however attractive the service, however faithful the pastoral visitation, none of these things can damage him or his kingdom if prayer is neglected.

You can't focus on other people's careers. Everybody is different.
