Most startup fail. There's at least one way to increase your chances of success, and it's on your second and third businesses. If you've started a business before, you're more likely to make it a success.

What's the reason? Avni is the best person to ask. After shuttering her previous business, she founded Milo, a company that makes organization tools for parents. Her odds of success are higher the second time around, that's according to a guest post written by a certified serialentrepreneur.

"This, I think is the most important thing, and my guess is that if second time founders are more successful, that's the reason why," wrote Patel Thompson. I would ask others how to think about hiring and giving equity and raising money. I know how to do it and how I can do it better. It doesn't make it any easier, but I don't have the weight of my newness weighing me down at each turn.

It's likely you're able to raise more capital to do it with if you know the lay of the start-up game better. You're able to connect more dots because you have more insight and instincts.

She cautions that reading the game isn't always pleasant. Being a repeat founder has the burden of knowing when something isn't working and knowing that you have to make harsher calls. You cannot claim to be ignorant. She says that you have to make the calls more brutal.

The ability to work a lot of hours is a requirement for entrepreneurial success. You might think these qualities decline as you get older, but Patel Thompson has seen them stay the same.

My first start-up was a bit of an accident. She writes that she was curious more than anything and that she was trying to do right by a product that had just taken off. She knew exactly what she was getting into when she chose startup life.

It made me realize that I could make my life's work if I kept going. I knew it was a marathon when I started and have been pacing myself ever since. She says that it's still at a sprint pace but one that she knows how to maintain.

It's not all sunshine and roses when it comes to entrepreneurship. "UnprocessedPTSD" from previous businesses, over thinking, and ego-driven decision making are some of the pitfalls that serial entrepreneurs face. The complete post contains information on the advantages and disadvantages of being a second or third timeentrepreneur.
