yes!!.... get a lesson to learn the very basics, even if it's only one

not because it's dangerous to try to learn without one, but because it's a frustrating sport to get the hang of the basics.
Be easy on yourself and realistic, and be prepared to fight with it for a couple of months worth of "weekend sessions" to learn to uphaul, do light wind turns, and sail slowly in a straight line
some people do pick it up quicker than others, but for most it's a slow but rewarding process
