This depends on exactly what your goals and timeline are in your business. You should ask yourself if the business class you are looking at will directly benefit what you are doing in your business short term. Since you are trying to launch a business, you'll likely have to put in a great deal of your time and energy to lift off, so taking a business class could create unnecessary stress, unless the class is directly related to helping you launch. I think your attention to personal/business development is so great! But during this crucial time, be very careful how you allocate your time and only give the most important activities priority. I've seen people spend years and years on "learning" only to never actually launch anything. Best of luck!
