Trying consumes resources. Hence, upon preparing to Try Again, one may have at her disposal a different amount of resources, which in turn may make the prospect of success quite different, and as a result a higher up goal may better be served by trying another direct goal, more fitting for the resources at hand.
In an emotional frenzy to try, try and try again in the very same way, one may ignore the resourcing question, and act less less optimally.
One may wish to estimate a success probability for a given goal, given various amounts of relevant resources (which have to be first identified). Based on this probability curve, one should decide on a rational TryAgain strategy (choosing between the goal that was just tried and failed, and any competing goal).
