All of the former members of One Direction have started their own solo careers However, one of the former members, Niall Horan, admitted that their solo careers just aren't the same. I know in my heart of hearts that no matter what any of us do individually it will never be as big as One Direction. It’s a competitive world out there and if it’s a world where I can bring this sort of music out there and be somewhat successful, I’m happy with that.
