For the next market, buy when no one is interested, and do whatever you want after buying. Before you are financially free, making money is always your top priority. Sell when the market is bustling, don't have any regrets, and never be afraid of selling at a loss, because selling at a loss is the way to make money forever. When the market starts to get lively, everyone shouts that they should rush in without thinking, when all kinds of monsters and demons come out to say how awesome they are, when the fear and greed index reaches a new high, when the news media is full of advertisements, and when the Google search index soars, it will never be wrong to leave the market at this time.
