Yes I know what you mean
I did a trip last year on my own, to go to Slovenia to meet family whom i had never meet before and made the decision if i was going overseas i my own, that i might as well make it a trip to remember and see some of the world.
I picked up a world map and basically picked a point on map to where i would have to get too for my ticket home (Rome) was my mark.,
Went by plane to Singapore, then Germany, Austria, then Slovenia.
Then took trains from Slovenia to Rome.
Not quite backpackers as booked apartments and hotels and stayed with family in Slovenia but had planned on also using B&B if needed too (heaps on internet.)
What a awesome experience and adventure and had opened up eyes up to what life has to offer.
And yes I going to do it all again next year but going to go to more countries.
So I say go for it
