I quit for about 5 or 6 years and it was the worst thing I ever did.
After sailing for about 5yrs, I stopped sailing for a season due to wrist problems and then started spending more time with my hotted up car .... and then sold the WS gear to buy car bits. Shame.
Next thing I knew I had not thought about WS'ing for a few years.
One day I drove past the beach in summer and saw the guys going off in 25kn .... almost brought me to tears, and I thought "what the hell have I done?".
Borrowed 2K the next day, bought gear and started again. The hot car lasted another 6 months before I didn't want sand in it and it was gone.
Now been back in for 8yrs or so and the wrists have never hurt, not once. Ankle and shoulder different story

but I won't quit now until I physically can't rig up anymore.
