Entrepreneurs make a lot of mistakes. By nature, we trip, stumble, and fall repeatedly. It’s disheartening, sure, but it’s what sets entrepreneurs apart from others – we always find a way to push forward. While each entrepreneur will inevitably make unique mistakes, there are certain traps that we all fall into, no matter who we are. Here are five that I’ve noticed as an entrepreneur.

1. The First Venture Will Be The Only Venture

Starting something new is absolutely exhilarating; it’s an experience that can’t really be described through words. Watching something you create, especially a business, grow is why entrepreneurs do what we do. However, it’s far too easy to embark upon a new venture and think, “This is it; this is the big one.” Unfortunately, it takes more than a few tries to get a business right. Name just about any successful entrepreneur – the venture that made them successful was not their first, and it’s something that every entrepreneur has to keep in mind. “Every entrepreneur overestimates the value of their idea,” says Matthew Work, CEO of Quick Left. “My experience is that execution, timing and luck vastly outweigh the idea in determining a venture’s success.”

2. Big Headedness

Another mistake we make is allowing ourselves to get arrogant. Confidence is a critical aspect of entrepreneurship, but there’s a fine line between confidence and cockiness, and every entrepreneur has, at some time or another, found themselves with their head in the clouds. We have a lot of reasons to be proud of ourselves, but nothing good comes from having too big of a head on our shoulders. The process of realizing that you’re not perfect isn’t an easy one, but it’s one that every entrepreneur has to experience to move forward.

3. It Can Be Done Alone

There are exactly zero entrepreneurs who have found success while going entirely solo. They simply don’t exist. That doesn’t mean that we haven’t thought we could at some time or another, though. The issue tends to lie in people thinking that collaborative efforts somehow remove legitimacy from their work, a mindset that is extremely dangerous, but altogether common. “Your team is your biggest asset,” says Dabble CEO Jay Swoboda. “Your time is precious and trying to do it all yourself will result in a lot of projects that are all half-completed. Your team can power through details, freeing you to focus on the big picture and get the right people on the bus.”

4. Ignoring Those Around Them

Similarly, entrepreneurs may learn to surround themselves with a great team, positive mentors, and friends who are willing to support them, yet they keep their eyes focused solely on themselves. This is generally a more passive mistake, as entrepreneurs tend not to realize that they’re making it. That doesn’t make it better, though; attention absolutely must be paid to those around you. Take time to acknowledge how much they’ve helped; after all, without the right people, a great entrepreneurial venture simple wouldn’t be possible.

5. “What if…?”

The two most horrific words an entrepreneur can utter are, “What if…?” They’re dangerous words, and they represent every negative thought an entrepreneur can have. The issue? We’ve all said them.What if it doesn’t work? What if I fail? What if I can’t do it? Then you’ll learn an important lesson and move on, that’s what will happen. Entrepreneurs don’t deal in hypotheticals. We have an idea and we make it a reality.
