Rather than thinking about your loved ones when you are not with them, make sure that when you are spending time with them you are completely present. This will greatly improve all of your relationships with people!
There are times also when we deliberately practice “selfless” giving, that is we are consciously helping others in order to get outside of our selves. This is a core practice in all paths of self improvement, but again the key is being completely absorbed in your current task. If your current task is helping others, you should be helping them to exclusion of everything else.
