Speaking to UEFA.com, the in-demand winger stated that the last four years have seen him progress with both the Portuguese national side and Manchester United.
The Golden Shoe winner said, "On a personal level I've grown a lot as a player because at my club, just as with my country, I'm surrounded by great players and it's easier to become better when things are like this, because it's easier to enjoy your football. We're always learning."
While the debate over his future at Old Trafford rages on, he's more concerned with Portugal's prospects at Euro 2008 after their near-miss four years ago in Lisbon.
No Ill Feeling
Ronaldo, then, is eager to make amends for what happened against Greece in the ill-fated final, and deems himself ready for the challenge.
"I feel really good on a personal level," he continued. "I feel I can do something good at EURO 2008. I'm impatient for the competition to start so we can give our best and I think everything will go very well.
"The team's evolution has been very positive. I think the squad have grown a lot since EURO 2004, as we showed at the World Cup in 2006.
"We improved in the qualification matches, which owed much to the staff and the coach we have, who have a lot of experience and who have won a lot of things."
More To Come
With a Premiership and Champions League medal in his drawer already, the ex-Sporting man is unfazed by the challenges to come.
"I think I made history in the Portuguese Liga and I think I'm continuing to make history at a European and world level, but we can always improve," he said.
"I have a lot to learn but I have the pleasure of being in a group that helps me improve constantly, as a person and as a player. History creates itself over a number of years, not in a moment, but I think I'm on the right road."
