Do me a favor will you? Stop Googling online on must visit attractions and must do stuffs prior to your trip. Throw that guide book away where there are hundreds of must try must do stuffs, and you ended up trying too much and getting disappointed.
Is understandable that some of us tries to make the most out of our trip. But making the most out of the trip doesn't mean you should get yourself stress up or tense up trying out every single thing written on travel bible.
Because when travelling involves a certain number of must do must see things, it might no longer be fun, instead try to have an open mind, let lose, while the city or places guide you through its charms and wonders.
Don't force yourself to the museum if you're not a fan of it, as you won't see any different there, it will just be a museum for you. But when you let go of that stubborn thought and do something you really like for example hanging out at the local bar or hunting down for food, then you find something you could relate to, something that makes your trip pleasant and makes you happy. You will go back satisfy with good memories well kept with you, and that's what really matters. And that's the time when you start noticing things around that others don't, which means you're having a trip of your own that's different from what others have, an experience unique for you.
