I think it's pretty crazy to say you've been typecast at the age of 20 before you've even really started getting going.
The more you travel the better you get at it. It sounds silly but with experience you learn how to pack the right way. I remember one of my first trips abroad travelling around Europe by rail fresh out of high school. I brought all these books with me and a paint set. I really had too much stuff so I've learnt to be more economical.
