Money well spent:

Supplements. 最值得的没有之一。 小小一瓶Vitamin D3，Vitamin B，带来的是全身心的变化。

体检。 不用多说。

床品。 Quality of life 和幸福感巨大提高。

ChatGPT subscription fee. My confidante and best friend.

一双舒适的鞋

最不值的：

Designer handbags/shoes/clothes/jewellery

Took me years to finally become certain that I do not like any of these things. They are all a waste of money and space.

所以only buy things that are functional, things that you actually like and will use on a daily basis
