Worry

Thinking ahead can help achieve one's goals - and is adaptive. To disambiguate from worry - worry is 'thinking about future events in a way that leaves you feeling anxious or apprehensive'. This is not adaptive. Worry is ok for 'real event worry' (specific triggers) but not for 'hypothetical worry' (habitual worry without specific triggers)

Other notes:

• Worry is related to intolerance of uncertainty. (reminds of authoritarian personality discussed in Radical Man - the radical tolerates ambiguity well, the conservative likes more structure)
