but is there a known way to put back some stuff from the experience bag to the luck back again?
I know nothing of your age or experience.
However I suspect you had little, if any, practical mountain flying experience when you posted the first video.
If you are still running into difficulties ( stuck above cloud for example) then I wonder if you are biting off more than you can chew at this stage of your experience.
Maybe if there is any doubt about weather/mountains/water crossings etc, you should consider some time with an experienced pilot/Instructor before undertaking these types of flights?
That may refill the bucket!
