There is no doubt that buying the airplane tickets to depart from the starting point is one very important step to make the trip happen. Maybe even not so much practically, but psychologically.
I mean, if it was 1500 EUR instead of 500 EUR, we would buy them anyway - we can't be stopped by such a small obstacle as expensive tickets, right? (Well, we can't, but if we can pay little bit less, it could be worth the struggle, no?)
So, first of all we are very happy with the fact that at last we have reserved the tickets! Thats the most important thing, and a big relief.
