What differentiates them from common people? A key aspect is something as simple as their attitude and mentality.
Most billion-dollar ideas were considered out of the norm at the time of their conception. As crazy as your own plans may seem, you shouldn't dispose of them just because of this. If you're willing to work for it and you genuinely see a future, no one will be able to stop you! Once you devise a thorough plan for your project, it won't seem as distant to achieve.
Every successful person has reached the top because they were following their goals. You have to, obviously, set these goals first. What are you planning to achieve? From the moment you wake up until you go back to sleep you need to dedicate your actions to reaching your main motivations. It's also advisable to set small goals on the way to the big one, so you don't feel as if you hadn't achieved anything each time you take a step towards your ultimate purpose.
"Go big or go home". Your plans and goals can't be too small; there's no point in following them if they don't prove to be any challenge. If you reach for the stars, you'll have more chances to get there than if you'd settled for a kitchen lightbulb.
You can work harder than you've ever had, but it'll be for nothing if you quit when the first problem arrives. It doesn't matter how many times you fall, it's the times you get up that count. Your perseverance will show others how convinced you're with your business, which will make them believe in its success. This way, you'll be more likely to receive more investments and business partners.
If you're convinced that your project will fail, it'll fail. However, if you approach each problem with positive thoughts, you won't be stuck in a spiral of desperation when it comes to solving it. Keep in mind that it's not about naive and effortless positivity, which can lead you to believe that fate will solve all your problems. No, you'll have to get down to actually solving it.
It takes time to turn these attitudes into habits, but everything's possible with repetition. Granted, it can be hard at first, but once you've made it a daily occurrence to wake up with a set goal, or be ready to face all challenges, or build positive thoughts, it'll start to happen by itself. Commitment and dedication will soon be an always-present part of your mentality.
