Unplanned investment in this market is like a small boat floating on the sea, with the possibility of capsizing at any time. Investment does not enjoy preferential treatment because you are weak. The waves wash away the sand, the sunken are gold, the remaining are king, and we can only survive by fighting prepared battles. Don't forget about a single profit, nor feel overwhelmed by a single loss. Investing is about the overall benefit, not being arrogant or impatient, always striving for your own profit in the market.
