The fear of starting a business is more different than any other kind of fear. Starting could result in a powerful business that makes millions of dollars. Starting could mean you being able to earn a full-time income while working at your own hours and vacationing all around the world. Those are just some of the many benefits of starting your own business.
However, starting a business also means more criticism. Starting means giving yourself full responsibility to implement your ideas. Instead of playing it safe and getting paid to be employed, starting means putting the money aside to start something new that could bring in a lot of money later on.
Starting a business is like a double edged sword. While it does involve less money and large amounts of your time in the beginning, managing a business gradually becomes easier, and more revenue comes in. If you are willing to be patient in the beginning, you will be able to see your idea soar.
Once you come up with one thriving business, it will be much easier to grow strong followings for your other businesses. Once you already have a fan base, you will be able to get more new and returning customers when you create another business.
If you decide that your idea is worth it, if you are willing to put in the work and effort, and if you do not care if people will criticize you, then start the business you have been thinking about. You will have to build a team around your business, and that is fine, because no individual can manage an entire business on their own.
