One Direction fans, do you think that One Direction is starting to fade a bit? Is this the beginning of the end?

Look, I'm a huge One Direction fan and nothing makes me happier than seeing the boys have hit songs, a lot of album sales, and a lot of YouTube views. I've noticed that they haven't really had a smash hit since Story Of My Life. That song was massive, had a lot of YouTube views, and did well on the charts. Now, Steal My Girl and Night Changes haven't come close to the success of Best Song Ever, Live While We're Young, and Story Of My Life. Less YouTube views and lower chart positions point to that. Aside from this, Four hasn't sold as well as Midnight Memories. What's wrong? Has the quality of the songs decreased? I don't think so. Steal My Girl and Night Changes are pretty good songs. Has the fandom become smaller and lazier? I don't think so either. We just BEYONCE in the AMAs and we've seen how big our fandom really is judging by the sales from the WWA tour and OTRA tour. So can any Directioner help me understand why this is happening? Is this a mere "bad day in the office" or is it something more serious like the end of the road for 1D? Look, I want the boys to go on and make great music for decades to come. I want them to still be selling out arenas and stadiums while having hit albums and singles years from now. Is it time for a wake up call? What should the fandom and the boys do so we can go back to

the glory days of 1D when we took over the world? Thoughts?
