If you are checking your phone at 2:00 AM to see how the market is doing, you have too much money on the line.

Look for ones with $0 commissions (like Charles Schwab, Fidelity, or Vanguard).

Before you touch a single dollar, you need to understand what a stock actually is. When you buy a share, you are buying a tiny piece of a business. If the business grows or becomes more valuable, your piece becomes worth more.

Learning to buy and sell stocks is 20% mechanics and 80% psychology. Start by reading, practice with fake money, and when you finally go live, start small. The market is a patient machine that transfers money from the impatient to the patient.

Start with The Intelligent Investor by Benjamin Graham (for safety and logic) or One Up on Wall Street by Peter Lynch (for finding great companies in everyday life).

Most major brokerage apps (like Thinkorswim or Interactive Brokers) offer "simulators." They give you $100,000 of fake money to trade in the real market. This allows you to make "rookie mistakes"—like accidentally buying the wrong ticker symbol—without losing your rent money. 3. The Strategy: Picking Your Lane
