According to CNBC, here are insights from accomplished self-made millionaires and advisors from the Oracles, who share their guidance on prevalent behaviors that hinder individuals from attaining success.

• Grant Cardone, founder of Cardone Capital, says, “Not showing up is the No. 1 reason most people fail, and it’s a very common and easy mistake to make. Showing up again and again requires faith and persistence, but it also creates discipline. You’ll never conquer what you don’t move toward. If you don’t make any moves, you’ll become stagnant, unmotivated, and ultimately spiral downward.”
• Michael Ovitz, co-founder of Creative Artists Agency and former president of The Walt Disney Company (NYSE:DIS), says, “It’s tempting to be lazy. But if you want to achieve great outcomes, you need to put in the work. I was raised by parents who told me that I could do whatever I wanted to do and be whoever I wanted to be as long as I worked hard for it. If anything, I probably work too hard — but that’s exactly what it takes.”
• Barbara Corcoran, founder of The Corcoran Group and “Shark Tank” investor, says, “I used to think I could change someone with a bad attitude, but I have since learned to fire them. It only takes one negative person in a group of 10 happy people to bring the whole team down. But nothing gets in the way of someone who says, ‘We can do this.’”
• Holly Parker, founder, and CEO of The Holly Parker Team at Douglas Elliman, says, “The power of smiling is underrated. A warm, genuine smile instantly creates trust, the cornerstone of every business transaction. Not only does it add positive energy to your expression, but it also makes you seem approachable.”
• James Daily, founding partner of Daily Law Group, says, “Pick one thing you’re passionate about and do it better than everyone else. Too many people have 1,000 brilliant ideas and never start any of them. Instead, they get involved in everyone else’s business.”
• Alon Rajic, CEO of Review Home Warranties, says, “If you want to achieve your goals, let go of the common belief that everything is within your control. Sometimes, you just have to accept the reality of a situation, be decisive and allocate your time to where you can truly make a difference.”
