I don't ever feel pot commited, and this isn't the first time I've mentioned this here.

In relation, however, the only time I feel a good decision is to call on the river without the nuts is when I feel my read gives me good pot odds to call.

example: I think I am winning at least 10% of the time in a situation where villain bets $10 into a $90 pot.

This isn't an obligation or commitment though, just a good decision.
