Hi
have a look at the ego thread some of the replies may help.
You have free will basically to say yes or no to what is.
You have the choice to acept your creator or reject but heaven help you if you do that -- smiling.
Choices are limited.
Even if you work hard to acheive some things no mtter how much you want them will not materialise.
Your existence is eternal so you have no choice on that one.
You can improve your existence.

No doubt you will get some wise answers here to your vaild questions.

Wishing you well
Chris
