$BTC $ETH
Among all assets, I believe that one must hold some Bitcoin and Ethereum to some extent, regardless of the time, because the global economy is unstable, and you never know if the currency you hold will depreciate significantly. Having a certain amount of Bitcoin and Ethereum, along with gold, might help withstand many impacts.
However, if you make money, you still need to enjoy it. Sometimes when a person falls ill, they start to wonder what all that money is for; if one day they pass away, that money becomes useless. So, one should go out more often, and see this vast world. Walk around in this world more.
