You have to believe in the long term plan you have but you need the short term goals to motivate and inspire you.

I never expected i, in the first place, when I started playing tennis, that I would ever carry the flag into the Olympic Stadium for an Olympic Games... So for me that was a surprise and a huge honor in my life to be able to represent Switzerland.

When you're good at something, make that everything

What I think I've been able to do well over the years is play with pain, play with problems, play in all sorts of conditions.
