What is Life???

Whokay, I am gonna blabber something here as I woke up this morning and I was motivated to change a few aspects in my life. Have taken first step for one of the things this morning and I now I want to blabber did not want to talk to any of my friends or family members, hence this blog.
These days once again I am thinking about very basic questions, which I have seen hovering over my mind before too.

What is life?
What should one do to live the life in the most optimum/ideal way?
Why am I on this earth?
Is it by chance or was it a part of some plan as some people do seem to believe?
Everything becomes a routine, then howcome people managae to be happy always?
What keeps people going?
Can someone be truly happy without being spiritual?
Why is it so difficult to be a good person?
What is required to be a good person?
Why do we belittle stuff? Why can't we be respectful of stuff?
Is is true that we are what we think we are?

I am starting to feel little emptiness inside me again like I was feeling in usa. Its not at all as great as before but yet its there. I feel that I need to change something in my life. I feel I need to start to be a part of some social communnity and work towards some long term goal helping people in some way, create a difference. I know it all sounds very common and whoever is reading must have heard the exact same words before. I used to feel the same and I think I know now what someone means when they truly use these words. Well its just a thought, the solution to the emptiness inside can be something else but hey that's what exploration is all about, one does stuff knowingly or unknowingly and if one is observant enough a lot of pleasure/knowledge can be extracted through these. I need to start socializing more, my biggest turn on is people which brings out the good in me and my biggest turn off is people which brings out all the bad in me. What an irony! I understand now why it is said that how and why forgiveness is important. I think it is necessary to protect the good in oneself from external contamination and it makes one insensitive to external negative fluctuations. Buts it sure feels hard to practice. Whoa am lost in my thoughts, I think I should stop and work towards the stuff I decided this morning.
