only a fool assumes apriori that an optimist falls for the illusions of others... i'll repeat, after all is said and done, all the worrier gets for his trouble is an ulcer. you have to enjoy life RIGHT NOW, and that in no way assumes one is not preparing for the future. i bailed the market COMPLETELY in late 1999 and have not returned, yet i am an optimist, and enjoying life very well, thank you.
being a worrier in no way implies making the correct, or the incorrect call. ditto the optimist.
it is all a matter of attitude towards life. if you want to be a worrier, suit yourself. i will remain an optimist, particularly in the area i know best, my own intuition...
