I'm not nice, I just don't know how to say no

I'm not nice, I just don't know how to say no.

Many of my friends and people I know tell me that I am generous. But for me, I think I still can't distinguish between the times when I am generous and the times when I just can't say no.

I once wrote about how I was fed up with how some people used this to get what they wanted.

Since then, I've been trying to find a balance. To help when I can and to reject when I can't. It's not always easy. But at least now it's in a corner of my head and I'm trying to hold on to it.
