She loves to travel and has already visited many countries and regions in Europe. She enjoys the occasional glass of wine, but doesn’t drink much. She’s single, has no children, is a minimalist, and doesn’t wear jewelry. She enjoys journaling and is passionate about reading. She can afford anything, so I’d like to give her something heartwarming. I also think she has a masculine soul and is full of wisdom. We’re only a few years apart in age, and I’ve always admired her drive and independence. I like to support small businesses, so if you know of any, please share the link with me.

LIKE I SAID, the trick to gifting people who can afford to buy anything they want and need is to give them personalized and, like you said, thoughtful gifts without worrying about the price (i.e., they can be cheap).
I would look for something personal or unique: spices, a candle, a nice tea set, etc. That way, it stays minimalist when you use it. I have some great ideas here; maybe they’ll work for you too?
