Johanna Konta says she can significantly improve her game despite reaching the Wimbledon semi-final and fourth in the world rankings.
The 26-year-old British number one is taking a short break ahead of preparation for the US Open in August.
"I think I've got a massive amount of room to grow in all areas of my game to be quite honest," she told BBC Sport.
Australian-born Konta said she is proud to represent Great Britain after her nationality was questioned.
'Leaving no stone unturned'
Konta became the first British woman since Virginia Wade 39 years earlier to reach the Wimbledon last four.
