Salkantay is a great trek too, as for Laugavegur I would have to go back to Iceland and do that one, it looks amazing! (how long was the trek? Did you prepare/book long in advance?). Well yes travelling is great but it's not the answer to every problems, it's a way to know yourself outside work, which is more important in the end. And yes I completely agree with you, you just want to travel more, it's really addictive and I take it, it's because it gives you a lot of enjoyment as life should be.
