Who am I? My past or future?

I know that I am my present. But what my present really is?

Conventionally, it is assumed that what I learnt in past, what I experienced in past and what I did in past is what defines me or decides my present...

But most of the things that I always do is either because of fear of the future consequence or gains I expect in future. I studied engineering to get better career options. I do hard work as I want salary at the end of the month. I write this blog as I want people to read and appreciate it... Everything that I do in present is based on what I want in future. And that is what becomes my past which defines my present....

So now, who am I really? My past or (expected) future?
