I was surprisingly impressed with Amsterdam, compared to all of the stereotypes associated with it. When I spent a summer in Europe, Amsterdam had the safest and cleanest public transport (in my opinion), the parks were lovely, and the people were so friendly. Then again, I was also there during the Euro Cup 2012, so the camaraderie was flowing within every pub if you said you were rooting for their team.
TO DO // Pics or it didn't happen. You were never truly in Amsterdam unless you get a picture in front of the "I Amsterdam" letters display. Add some culture to your life: visit the Van Gogh museum and the Anne Frank House. Take a cruise around the canals; it will make you want to live on a houseboat for like 30 minutes and then you'll change your mind.
Be a true tourist and go on the Heineken Experience tour. Being in marketing, I will say they definitely understand experiential branding.
One last one: look up whoever is playing at Paradiso and go. Even if you don't like the music, just go. This place used to be a 19th century church with amazing stained glass windows and is now one of the top nightlife places in Amsterdam. You are guaranteed to have a good time, just trust me.
TO EAT // Everything on this list. But no matter what, you have to get some chips from a street car and add whatever sauces they're offering.
TO SEE //Vondelpark. But you really need to see it and take in everything: the yoga session going on to your left, the kids running around to the right, the way the sun sets on the surrounding buildings. Pause your life and enjoy the peaceful moments. Oh, and don't forget to squeeze in a day trip to the tulip fields.
