I was super shy and nervous all through school(nerdy outcast type kinda). But, around 19-20 I knew I wanted to do something different and adventurous. Finally, after a few failed attempts(backing out last minute) I finally ended starting my travels by hitchhiking. And to this day I'm still nervous and scared when I travel :O :O
If you want to do it you definitely can. :) Also, thanks so much for the compliments @lewik. Much appreciated.
