Last minute trip to Taiwan

Hello all. I’m going to Taiwan for 7 days (6 nights) in a couple of weeks and I’m wondering if it’s worth splitting the time across places? Fly into Taipei. Absolutely love modern/contemporary art, and then all the usual - food, nature, shops, museums - love anything a bit edgy or macabre. I am defo a city girl but do love nature and open to anything really. I am flapping a bit as I usually I obsess for months over itineraries and I’m short of time which is making me very indecisive. Help! (Please 🤗)
