There's a theory amongst the Buddhist types, best articulated by Pema Chodron, where "chasing" after a feeling pretty much guarantees you will not reach it. That if you allow the feeling to just be where it is, accepting it will come and go without much personal ability to change that, it will appear more regularly.

In my experience, there isn't a lot wrong with this. Implementing it is never consistent, as the idea itself would suggest. Noticing that my connection to anyone can feel stronger or weaker at any time is often a good first step. But for me, trying to "fix" a sense of fading connection like a meal satisfies hunger has not worked.
