I wonder how many of the usual suspects (to use a convenient shorthand) that have produced books / DVDs etc about their travels would say that their output matches the intensity of their experiences. Very few I would imagine. Back in my early bike travel days we used to keep daily journals to try and a) remember as much as possible and b) be able to relate what we'd seen to friends / family when we got back. We very quickly learned that most people don't want much more than a 2 min summary with some amusing anecdotes - it was sunny / freezing, we ate some very odd food and the toilets were weird / disgusting would do it most of the time. Digging out more than two or three pictures got the subject changed pretty rapidly.

I was lucky to some degree in that we had a loose bunch of us who did various trips and now and again (usually in the winter) we'd have a "reunion" in a pub somewhere where you could be a little more certain of a sympathetic ear - a bit like some of the HUBB meets these days. I'd suggest you put all your thoughts, conclusions and wisdom (together with the best of the pics) into some kind of concise form and do a presentation at some upcoming gathering. They're a bit thin on the ground this year in the UK I admit but a substantial trip has a bit of a lifespan so next year / the year after would still be ok. Failing that a book (hard work but it can be very satisfying) or (for video / stills) something on line.

Probably the worst thing to do is to leave it as a "I'll get round to it " project because the act of having to distill the experience for the page / talk does condense insights that otherwise remained half formed. For some of my trips it was years if not decades later that the core lesson to be learnt became obvious.
