Avoid computers and phones because new models come out so fast they are hard to sell if they get too old.
This reminds me of the fact that the way we often channel Money when we have it can sometimes prove instrumental when we no longer have money. I wasn't born rich, infact I am not rich, but just trying to stay minimal making sure I buy what I truly need and spend on comfort rather than luxury. I do not own a lot of properly too, but then I figured out that owning one's wealth in tangibles that can be trails is is often beneficial. eBay is not really a thing in the country where i'm from, but we sure use to have a market where second handed goods had a huge industry.
