Lleyton Hewitt said he would continue to look for ways to improve after suffering defeat to Roger Federer in the Wimbledon semi-finals.
The world number two has now lost his last eight matches against Federer.
"You just have to bide your time, keep grinding away and keep looking for answers," said the Australian.
"I feel like I've lifted my game and I have no doubt I'm the second best player around. It's just that the best player is pretty bloody good."
Hewitt won seven of his first nine encounters with Federer, but has now lost 15 consecutive sets.
However, the 24-year-old said: "In some ways it's a huge positive that I can keep putting myself in these positions.
"I'm doing something right to come awfully close so many times.
"I can't remember in the last 18 months losing a bad match to an average player."
However, Hewitt would not be drawn on whether Federer was the best player he had ever faced.
"When Pete Sampras was probably at his best, it was probably just before I got on the tour and was competitive against those top guys," he said.
"Andre Agassi at his best, he was great as well but he hasn't been quite at his best since Roger's been playing his best tennis the last couple of years.
"There's no doubt Roger's in the top few with the greats."
