First of all: Talk to me!
If you are still unsure because of the missing guarantees; when you do not know if you want to go on such a trip, I recommend you to NOT start that adventure!
Only if you are ready to react flexibly on unpredictable situations, are ready to get yourself into a little adventure and are able to deal with the small defeats of everyday living, then your are on the right way and ready to go on this trip!.
