According to The Sun's Dan Wootton (via UnrealityTV), "Close friends [of Harry's] tell me he's more than happy to spend at least the next two years devoted to working full-time with his bandmates."
As always, there's conflicting information, with a source telling Daily Star: "Harry's a very sensible man. He knows he's got time on his side and doesn't want to rush anything. Right now he loves that his life in One Direction means he gets to meet so many interesting people who might be able to help him in the future. He's very grateful for everything One Direction has given him."
And, bottom line, it's all about the music, with a source noting, "Plus, they're actually still making amazing music, which is the most important thing. But obviously he does think about his future and what he might like to achieve. That's inevitable. He's ambitious about his future."
