Wondering...

Sometimes it's difficult to explain what's going on in the head. Sometimes only a look is enough. Why does this happen I wonder. The complexity baffles me to no extent. Can something be so simple and yet so complex at the same time?
Sometimes it's a fight between saying it and keeping quiet. How does one know the choice they made is correct? It's obviously after it's either all gone wrong or when things start to fall into place. In both the circumstances the decision cannot be reversed. Then why is it that the decision itself becomes so troublesome? Neither the pain or the happiness will be everlasting. Then why does one have to think so much?
Countless contradictions. How do we decide what's right and what's wrong? What's true and what's false? They say victors decide the truth and truth births righteousness. So truth becomes an idea that was molded by numerous victor's over the millennia. And so there cannot be one definite truth in existence.
