I feel as you do Puckster.
After years of wilderness trips under time restraints, I decided that when I retire I'll be able to "mosey" when I feel like it.

I know from my too early Spring trip, I can "go hard" if need be, but why do that unless you have a deadline to keep or want the physical challenge. Been there, done that.

You mention that being a solo paddler isn't for you? Just a thought, but being solo, free to "mosey" is much different than being solo with 
a schedule to keep and the work required to make that happen.

Maybe reconsider that solo thing for a short trip just moseying to see IF that changes your mind?

I think OS's advice is good too. Planning shorter routes with options for day trips is a great way to " work smarter, not harder".
