How can you be genuinely kind if you are not?

I think an example might be, if you see someone say, struggling with a door, and they have a big bag in their hands, at a store or wherever, and you are going by, to be kind, would be to see, 'hmm I know that is hard for me and 'I'd" like a hand if I were them' and then offer to open the door. I think it just comes down to seeing yourself in another. I love Byron Katie and her deep philosophical work.. she says 'When I look in a mirror, I see you'...meaning we ALL have thoughts, feelings, and wants, we all suffer or feel a bad day; so it's really just helping 'you' in a way when you are kind to another.... it is almost like you were being kind to you- when 'you' were in that situation. That's just an opinion, I'm no expert on kindness.... and people are RARELY kind to me, as in go out of their way to smile or hold door etc. But, it occurs sometimes, and I think, 'wow that was really nice' (for ex. someone came to a stop on a busy road to let me out of a side street ... there was no traffic for them to already stop in, so they did it just to be kind. I appreciated it)

People can change if they're highly motivated to do so and are willing to work at it. I believe this applies to a desire to be kinder as much as anything else.

I can only really state what's in my opinion but if you are not kind to begin with then that's just who you are. I understand.

I don't really know what to say to make it feel genuine but the thing that helps me when I don't know how to connect and often I don't is just to look at things from their perspective.... when I really want to understand anyways.

It may not make you "genuine" but it could help to know what their feeling. Generic advice but that's the only way I can think of to get a genuine feel.

You gotta fake it till you make it brother.

I think people can change. It takes more work for some then others.

You can consciously choose to do something that in others would come as natural kindness. That conscious choice is also being genuine in intentions.

In someone's nature it can't..but people can be genuinely nice in certain situations.

Just think to yourself, what would Jesus do

I think it's something you can learn with some time and patience. Not easily of course.

No core characters never change.
