Considering I ended up on a 16 hours long flight I had plenty of time to go over all the answers in details and make proper notes. When I started this thread I was indeed vague, because I had no idea of a lot of things and didnt know how far I can push this , now and later in years from now, your answers greatly helped me put a picture together.
My ultimate and ideal objective would be to end up sailing around the world, not a "race" sail, but going with the flow and the wind wherever, my home being a boat in every sense of the word and the world being my backyard. This fits very well with me personally, my mindset and my interests and loves. But honestly for years I just considered that as idealistic thinking.
I thought of starting now with getting used to boats, living on boats, sailing as much as I can to gain experience. And for the moment keep working. What I realized now is that there is no way I could sail longer distances ( ie. 3 weeks) and still work on the boat at the same time, regardless I have internet or not. It would be downright irresponsible for solo cruising, the boat doesn't sail itself. So for now, as denise said, I will focus on gaining sailing experience and learning about boats from every aspect, what would I want and expect from a boat, crew on some as I also learnt is also possible even if my experience is small. If after that I still want to go on, buy a boat, fix it to my needs, choose a nice and convenient marina for me considering the occasional trips too, be there for 6 months or one year, good internet next to a marina now I see its very possible thanks to SVAuspicious and svzephyr44. Weekend sails, experience gaining, and then I can start to hop from marina to marina, these are shorter trips, and then years from now internationally but not working while I cross. I even learnt that I can hire someone to sail my boat while I fly there and hence keep working. Although I would worry a lot. My life would be on that boat.
In rest, you all addressed very good points, but if you personally knew me, you would also know that they wouldn't be big issues for me, ie, small space, small bathroom, limited things, limited water, cooking in small places with hardly any kitchen appliances, etc. , learning diesel engines and plumbing and electronics, that will be fun for me, not a chore. Carrying water and emptying sewage, part of life like anything else, doable. I would seriously run from winter on a boat, that's not me! There I draw the line.
What truly worries me is feeling seasick because I am too much on a laptop on a rocking boat or not being able to do my job on a boat because of that or other reasons.
The other thing that worries me is not being able to handle/sail the boat. It does require strength, and on serious winds that becomes an issue and risk, for me and for all of you out there.
I don't say that women are less capable then men, but even if I want to change the tire on my Wrangler, I can tell you, its not a small tire.
All in all, you all helped me put a part of the puzzle together and now I see maybe this is not an idealistic dream after all.
