Planning and preparation.
If I have too much to do, I get paralysed by fear of failure, so I make sure I don't take on more than I can handle. I've learnt to spot the signs of impending paralysis so I can dump less important stuff before it actually happens. Which is why I haven't been here lately.
Specific situations like speaking in front of a group can sometimes trigger anxiety attacks for me. However, I know that if I prepare well enough I'm able to hold a decent presentation in spite of having an attack.
Then there's waiting for the bus that never comes, worrying over being late to something important. Things that are beyond my control. Then and only then I have my trusty relaxation technique of taking a deep breath and letting it out sloooowly. I've actually begun to do it subconsciously, all of a sudden I notice I'm breathing that way and think "Huh. I guess I was fretting about something."
