I finally understood multithreading — and now my code runs 10x faster. Multithreading used to sound like magic. Or worse — a trap full of race conditions, deadlocks, and endless debugging. But once I broke it down, I realized: It’s just parallel thinking with safety checks. Here’s what helped it all click:
🔹 Threads = multiple tasks running in parallel
🔹 Mutex/locks = only one thread can access shared data at a time
🔹 Race Conditions = when threads clash over shared state
🔹 Deadlocks = when threads wait
