Oh dear.
Solar radiation does not diminish by night. Hotel stays are not the highlight of professional aviation, well generally not.
Best to clearly understand that what it takes to get there is a will to succeed in flying that doesn't question the negatives too closely. These exist to the same degree as any job, and can be quite a pain.
It's the positives that count, but they only come from a real desire to fly an aircraft professionally, i.e. in all weathers, to a high standard, mastering complex and beautiful aircraft, and managing the problems successfully. The negatives are in abundance, as they would be for a desk job with the council, a marketing career with a blue-chip, advertising to the masses, high profile politics, and so on.
Mind you, James Bond seemed to have a decent non-flying job.....
