Warren Buffett's top investment advice: "Before buying stocks, make sure you're prepared to accept a potential 50% or 80% drop, and still remain calm before you make a move." To truly make money in the market, you need to do the following: 1⃣ Make decisions with a 10-20 year perspective 2⃣ Don't focus on daily fluctuations or be driven by short-term volatility 3⃣ Dare to add to positions during major declines, avoid chasing highs during big rallies, and be willing to act when others panic. 4⃣ Don't frequently refresh your account, reduce internal friction.
