Or a phobia....
For instance - I'm afraid of about four things - moderately afraid of heights and the dark, severely afraid of spiders and worms. Not sure why, no pivotal childhood trauma, no real reason.
If Steve has a similar irrational fear of something I'd love to see a 30 day trial of getting rid of it. Either through desensitization or whatever other methods are available. That's pretty conducive to personal development and may inspire many others to do the same.
Course you have to have a fear first, but seems most people harbor one or two irrational fears somewhere...
