What is the contradictory mentality that prevents you from success?

Why is it said that ‘failure is the mother of success’? Looking back at the historical books of ancient and modern times, China and abroad, many great successes are a series of failed stories. Every major scientific invention has experienced hundreds, even thousands of failures. The biggest difference between those successful people is that they can get up no matter how many times they fall, and be good at learning lessons from failures, and take a step forward after each failure. Failure is not an obstacle to stopping, but a step to keep climbing. To be successful, you must first set a goal. If a success is compared to a ship sailing around the world in the sea, setting a goal is like setting a road map, and the ports you have to pass along will become medium and short-term phased goals, and finally achieving the ultimate goal of the world. If you don’t set a goal, it’s like a piece of wood drifting smoothly. You may be able to float to somewhere, but you will never achieve the goal of getting around the world, and you may always be drifting around at your doorstep. Mentality is a psychological state that determines our daily behavior, and it determines the final result of our work. The biggest difference between successful people and losers is the different mentality of doing things. To succeed, you must have eight mentalities: 1. A positive mentality; 2. A learning mentality; 3. A giving mentality; 4. A persistent mentality; 5. A cooperative mentality; 6. A humble mentality; 7. A grateful mentality; 8. A self-discipline mentality. Then do you already have the mentality of a successful person? If you don’t have it fully, then what is the contradictory mentality that prevents you from success?
