can't say i have an answer

So i've been reading this book by the dalai lama on happiness. I have to give it to him, i'm not in the very least an authority in philosophy, or religion, but the book is very good thus far.

Someone once told me that enlightment is so simple, it's hard to achieve because it's just so easy to miss.

I decided today that the first day of the journey is tomorrow. I wish i could take you all along with me, but right now i just need to be with my thoughts.

What is happiness to you?
