I am but hollow

 You assume that you've known everything. You are sure of things that you're working on is worth it.

You firmly believe that everything will pass, for better or worse.

You might stumble on things or two, but by the end of the day, it will serve as a learning experience.

You think that everything are reasonable;that by understanding how it is, you could prevent any problems.

You might see me strong and sharp, too serious for my own good. Unfeeling, unwavering. 

But in the end, it's just that. You may see me, but I am hollow. Am empty on the inside. 

I am but hollow
