purpose, interests, and rights

For a long time I thought about these and came up with the following conclusions:

• purpose of (my) life is experiencing life itself to the maximum as I fully develop and apply my specific abilities to it,
• nothing but my interests should guide my behavior, and
• there is no such thing as inalienable rights.

I know that this would surprise and even shock some of those who think they know me. I will elaborate later - it might make sense to you as well.
