好心真的会有好报吗？

Some time I do wonder if there is there a truth to this sentence "好心有好报".

My question is 好心真的会有好报吗？

Most of the time, I do things without self-interest just because
I am kind-hearted,
I was brought up and taught with the thinking to be a good and nice guy,
I believe in paying it foward,
I believe that what I can do for a fellow man/woman, they will do the same for me when the time comes.

But some how, some time, things are happening to me just make me wonder if 好心真的会有好报吗？Do karma and retribution really exist... it really make me ponder...

When we do good to people, we shouldn't expect any return and I do not ask people for a pay back of favour, but I also do not ask to be treated badly or unfairly in return.

I really have been doing a lot of thinking these days and start to examine into my life... Some time, I couldn't help but wonder, why do nice guy has to finish last.

But whatever that will happen, it won't change me because I am who am I. I cannot change to be bad... well... because it is just not me...

I do find that it is just so pathetic :(
All because of my upbringing and the "good, nice and gentle guy" persona which I had built over these years... Some time, I do hate myself...
