Anyone who has moved to Greece has done it by taking practical steps. So you don't need inspiration, OP, you need a practical plan.
Do your research.
What do you need to live in Greece? Do you have citizenship of an EU country and therefore freedom of movement? Or do you need a residence permit/visa?
What jobs are available? Could you do any of them? Is there a viable business you could run? What is the process of starting up and running a business in Greece?
Do you speak Greek? If not, how long would it take you to get to a level where you could deal with life admn (banking, buying/renting and maintaining a home, transport, taxes, healthcare etc) and work/business admin in Greek, spoken and written?
Would you maintain links with people in the UK and if so, how? As a PP has mentioned, what is year-round travel like?
How will climate change continue to affect Greece - wildfires, drought, life-endangering temperatures, effects on infrastructure and economy such as tourism?
