I've never felt nervous in front of big crowds and in big stadiums.

There is a fear of emotion in tennis.

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.

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.

It's difficult to relax on tournaments, even in posh hotels, because you don't know how long you will be there - whether you'll lose a match on the first day and leave or whether you'll stay for longer.

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.

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.
