Thank you Middle Path! You compliment is valued and appreciated. Same for you Oomis. I try, but naturally being a fast paced person, it takes some work to slow down and take time to really internalize and appreciate what the other person has been doing.
SilentOne, I think that what you are describing is someone who has an Ayin Tov/a good eye, who naturally looks toward the good of other people and toward the good of what they do as well. Someone who is a positive person will notice the positive attributes and actions of others. And, will also naturally appreciate others as well.
In terms of Chizzuk, I would guess its a two way street. Make her feel appreciated for what she does and for who she is as well. If she does anything for you, at all, no matter whether it is needed by you or not; if she has good intentions, thank her very much for that. And the best formula-in my opinion, is to constantly seek out the good in each other and bring it to the other person’s attention as much as you can, with it being natural of course. Again, this relates to having an Ayin Tov.
