If you decide to go for a bachelor’s degree, then it would take you 4 years to obtain one.
Firstly, identify the industry that you want to work in and only then go for a degree.
If you want your business to be connected with the technology field, for example, then the chances to succeed will be higher, if you get the right education.
It can take you a few weeks or a few decades to launch a business.
In any case, you would want to have a talk with a lawyer to ensure that your future business is legally protected.
