The serve, I was too young and too small and... not enough powerful to have a good serve when I was young, so my forehand was always my signature shot. So I used to always run around my backhand, you know, use my forehand as much as I could, and so that's why I think it's my strength also today, you know.

Summary

In this quote, the speaker explains that when they were younger, their serve in tennis was not strong due to being young and small. As a result, their forehand became their signature shot. They developed a habit of running around their backhand and relying on their forehand as much as possible. This reliance on their forehand continued over the years and now it is still considered their strength in tennis.
