I'd say practicing non-dualism à la Zen Buddhism helps a lot. In short it helps see through preconceived (or any form of) notions, such that one doesn't become attached, including to the notion of becoming unattached itself.

It points outs that the separation of our individual self from others can be seen as illusory, that we're all deeply connected. Sure my left arm is weaker than my right, but that doesn't make it "less important", and in fact thinking in such a way is preposterous. But might be useful in another context such as left/right balance for fitness.
