Don't make yourself a 'hostage to fortune'. You're in a hostile environment, you might need all the help you can get.
If the fan stops do you fold your arms close your eyes and pray ? No, you plan for a controlled descent, and a glide approach coupled to an arrival on a friendly piece of terra firma - if you're lucky !
I sail small boats. The most useful bit of kit I have is an auto pilot slaved to a GPS. It frees me from the tyranny of the steering wheel in almost any kind of weather. It's much the same in the air.
If solo longish distance flying in changeable weather is your forte then stack the odds in your favour. It makes a lot of sense.
