Ask HN: How to enjoy traveling?

I am traveling right now, I see a lot of different and interesting stuff, I try a lot of new food, I meet wonderful people around...

And still I really feel like everything is just... I don't know, maybe empty... Meaningless...

I don't feel like growing up...

It is normal ? How can I enjoy more my trip ?

For the record I am traveling in China with three good friend, however my Chinese is below poor and talk with local most of the time is impossible...
