If you were to stay on a deserted island for ten years, what would you be like before?

Ten years is long or not; short is not short.
I will be purchasing the following products...
1. With steady returns, they will subscribe to promising ETFs.
2. In terms of funds, they will select the top 5 funds with the potential to invest for 10 years.
3. In terms of stocks, they will choose energy stocks, technology stocks, medical stocks, finance stocks, and real estate stocks to start.
4. Of course, after being on a deserted island for 10 years, how can we run out of drinking water, daily necessities, etc. Without these things, it goes without saying that after 10 years, I'll probably see Grandpa Yan in 1 year, so buying as many investment and wealth management products is useless.
