why do you ride a bike? for me it is being closer to the elements - rain, sun, snow, wind etc.
In a car you are watching a movie, on a bike you are part of that movie ( I don't know where that quote is from but its not mine)
It ain't a quote, its a religion... ;-)
However...
When attempting to start long bike travels, I'd start small... explore a few back-roads in your neighbourhood, slowly increase the circle to get one with the bike, then a couple of 1 day, 2 day trips, etc... it can take a while to build the mental and physical condition to focus on riding over longer time, deal with the different ergos and the elements... for the untrained already 2~3 hours of riding are absolutely exhausting... worse in sophisticated, very twisty terrain...
I'd definitely attend some motorcycle safety lessons... such a training is hard work, pretty exhausting but benefits a priceless gain in bike control, thus confidence, thus joy when out on the road...
I'd also start with a good, experienced rider as "mentor" on the first few trips, preferable with an alike motorcycle, at least of identical fuel range... he'll have a lot of brilliant tips and tricks, you can look and learn on his road/traffic awareness and bike control in numberless situations, the team adds safety, confidence and fun to the task...
Learn to observe yourself, how to recognize that you're tired, dehydrated, hungry, cold, too warm... to
instantly discern that you're not focussed and why, and how to deal with it...
And during a longer trip you'll
always sag on the 3rd day, strange effect, but that's how it is... ;-)
Also don't entangle into too many tasks, rather avoid stress factors... like riding and photography/filming doesn't go well together, or trying to visit too many sightseeing-points in too few days...
