When I first started travelling more often I couldn't care less about luggage or travel accessories. I would shove my clothes in a beaten up suitcase, put it in the hold and use whatever handbag I was using at the time for hand luggage..
Many of years (and trips) later and all I can think is boy was I an amateur!
Travel accessories are the kind of thing where you can invest in them once and they will last a lifetime. I also get somewhat sentimental over luggage nowadays, I treat them like little travel companions who get to see the world with me, albeit mainly through baggage claim and hotel rooms.
