Fernando Alonso insists he has had a "perfect" career in Formula One despite being unable to seal an elusive third drivers' championship.
Alonso, 35, is a two-time F1 champion, winning successive titles with Renault in 2005 and 2006.
However, after switching to McLaren Mercedes in 2007, the Spaniard missed out on a third consecutive crown by just one point to Ferrari's Kimi Raikkonen.
He came agonisingly close with Ferrari in 2010, losing out to Red Bull's Sebastian Vettel by four points, before finishing just three points behind the German two years later.
But Alonso feels his F1 career has still been perfect, despite suffering heartbreak on three occasions.
"I have been so lucky in my entire career to fight for championships," Alonso told Formula1.com.
"Yes, there have been more good opportunities for me, but for one reason or another it did not happen.
"My career path also could have ended in karting! So everything is perfect for me.
"Probably success is the most important thing of the enjoyment of being here - you are here to compete. Being on the podium, winning a race or even a championship: these are the moments of ultimate enjoyment.
"But then there is also the joy about other things that surround F1! The travelling that gave me the opportunity to visit countries I probably would have never seen in another life ... I am happy with all the fantastic side effects the sport has given me."
However, Alonso has not given up hope of challenging for the drivers' title once again, believing McLaren Honda will be a force in 2017 following F1's sweeping regulation changes.
"With the new regulations in place next year we will probably get the excitement back as the cars will be much more attractive - and much faster," he said.
"Another championship is the ultimate target, and we are working hard on that project. That is still the target that Fernando wants to achieve!"
