I've been so blessed to experience the joy of travel during more than 30 years of my working life as a Railway Engineering Consultant.
I visited so many places on almost every continent and lived in quite a few of them for significant periods of time. Probably more than the average person.

In the early days it was first class travel and accommodation. Gradually more and more cost restrictions came into force, but still I never tired of the lifestyle.
it was only after meeting the lady who would later be my wife that I gave up the job and the lifestyle. It's just not conducive for maintaining a lasting relationship.

The only downside was not having anyone to share the many many special moments and experiences.
I did sometimes feel lonely but never enough to loose my enthusiasm or hunger for more travel
