For those who grew up in families with average economic conditions, like me, many seemingly common "common sense" ideas are only understood in their twenties.

For example, having crooked teeth requires orthodontic treatment, spinal scoliosis needs correction, and mild myopia can be significantly delayed during adolescence with the use of orthokeratology lenses.

Health maintenance and correction are most effective during the golden period before the age of 18. Additionally, in a multilingual environment, the younger a person is, the easier it is to learn languages, and a multilingual environment can promote brain development.

Even now, when I am already undergoing these correcting projects to become healthier and starting to learn some minor languages, it might still be a bit of a perfectionist pursuit. Occasionally, I reflect on these late at night and feel some regret; due to objective conditions, I could not do the right thing at the right time, and only at an older age do I realize the need for remediation.

Poverty has limited vision and cognition, but I am grateful for past poverty, which makes me more aware of the preciousness of opportunities. Missing good timing is a truly regrettable matter. Just like investing, doing the right thing at the right time is crucial; for example, starting to play sol meme in the early stage, buying anything, most of which went to 100M, while starting to play sol meme during the downturn, 10M is difficult.
