Haha it's a lot easier than people imagine - if you have no dependents, leave your stuff in storage or with your mum and get on a plane with some clothes, a laptop and £15k income or savings per year. Personally I bring climbing gear too. 500 quid a month gets you an epic condo in SE Asia with 500Mbps symmetric (I'm talking city centre with rooftop infinity pool). Visas can be complicated but it's far easier here than Europe. They only managed to destroy our freedom of movement in Europe, not the rest of the world.
