The Barcelona forward, who rarely gives interviews, was speaking at an event where he was unveiled as a global ambassador for Gillette who will also support his charity - the Leo Messi Foundation.
And the four-time World Player of the Year says winning trophies with club and country are of far greater significance to him than personal accolades.
"Winning titles with the team is more important to me than winning individual awards," said Messi. "I hope to win everything with Barcelona and obviously I hope Argentina can reach the World Cup final.
"Whether it is against Brazil or whoever it would just be a dream come true to play in the final."
The Argentine, who has recently returned from a torn hamstring muscle suffered against Real Betis in November, said he was delighted to finally put his injury woes behind him and get a run of games under his belt.
The 26-year-old also explained how he feels like a different man since becoming a father after his partner Antonella Roccuzzo gave birth to his son Thiago in November 2012.
"Fatherhood has changed my life considerably," Messi said. "It has been a great pleasure for us to welcome Thiago into our lives and to be with him from day-to-day.
"It is especially exciting because he has started to do more things. He is walking and moving about the whole place.
"Every day he does new things - he is a great source of happiness for the whole family."
