I have always wanted to trek the Inca Trail, ever since seeing a picture of Macchu Pichu about 20 years ago. Thing is though, its expensive. I have some money stashed away in ISAs/shares etc. I could spend some of it, and be dead careful about not spending anything between now and August. I rarely go out anyway. I haven't been on holiday for 2 years, apart from a few weekends visiting friends in this country. I live on my own, pay all the bills, but I don't smoke, buy designer stuff, my car is ancient but mine, and I have nothing at all on credit, not even on a credit card. So, theoretically I could go. But what if my car dies? What if the boiler gives up the ghost? What if.....? Should I or shouldn't I??
