I have cancelled due to a broken alternator wire (no charging), and
several times due to weather that seemed ok when I drove to the
airport but looked unacceptable after I started the engine.

I have returned home due to higher than expected winds aloft and
impact to a tight schedule.

This morning I cut short an instrument course lesson due to less than
optimal physical condition.

Bottom line: I can end or not start any flight for any reason. I did
not see the original thread but if others are inconvenienced so be it.
I fly safe.
