Same mistake right or wrong

I am almost running out of my prinsip toward certain thing. My concept for certain thing seems to be changed day by day. Am I doing the same mistake? What if the mindset really changed? What if the thing not turns out to be what I hope it to be? Eh…getting confuse, I just can say... let time show me the way, let my mood and feeling flying with my soul... Hopefully everything will turn out to be fine. Again, I hope.
