I thought more about this on my way into the office ....
If you decide to travel - there are some must do things IMHO
Visit the East, China, Malaysia, Thailand. Its quite a difference to the western countries. Try to get out of the city. No doubt you will be offered cheap gem stones (glass), and all sorts of great deals in these countries. The flora is just very different as are the smells and people. The food is fantastic.
Europe is easy - one Schengen visa gets you into alot of countries - Holland, go to Friesland, and do the coffee shops of Amsterdam. Germany - climb on the ICE and see the country, Austria do the same on the CAT. Austria, sneak across to the Czech Republic - good looking girls, good food, great beer.
Italy - Venice Milan (lake Como) and Genoa. Then head to the other coast - Numana and Ancona - big yachting industry there.Italy, my best friend was Uno Moretti.
France / Switzerland - Mont Blanc - very pretty. Switzerland, do a road trip from Geneva to Urich via Interlaken. See if you can find the point where French becomes German.
Do South Amreica - but the south part - start in the Argentine - BA - and do Uruguay same time. Best beef in the world. Peru, great hiking destination - into Brazil. Brazil is a bit like SA.Check out the Amazon - the sheer size of it is a mind fusk.
USA - Always a good place to travel because of the size. Must do NY, Washington DC, (Licoln Memorial, Vietnam memorial and the like), and while you are in the area, Niagra falls, across into Canada at the Great Lakes. Suggest the salmon in Hamilton, Burlington or Toronto.
The Arch at St Louis - gateway to the South, Florida - just like a big KZN. Reno, and Salt lake city - beats Vegas.
California LA - home of the stars - have to the Sanat Monica Pier, Venice beach and for a laugh, Muscle beach.
Cross over at San Ysidro to go to Tijuana - cheap booze, cheap drugs, cheap woman .... great experience.
No - you want my advice - travel. Its something nobody can take away from you, and builds chracter.
