What makes you valuable? How would you change your life to be a more valuable person?
Whenever I think about this question I usually end up with answers like: helping others, solving poverty and hunger, curing a disease, be appreciative of others help, etc. But there is something seriously wrong with this point of view. All these things are dependent on others. None of them describe my intrinsic value independent of others. What does this mean? Does the human not have any value intrinsically? If no, so what is the point of helping others; anyways if human has no intrinsic value, you are helping a worthless entity, therefore doing a worthless thing.
Therefore, one of the following must be the case:
1) Human has no value at all.
2) Some persons are valuable and the worthless people must seek value in contributing to them.
3) There is something valuable to each human being which is defined solely by the person him/her/themselves and not relative to others.

I am leaning towards the third. And I suppose the valueable thing in "helping others" comes from not the "others" part, but the "helping" part. So "helping" yourself is valuable too. But what is that thing? The thing that makes me valuable solely because of me?
