Looking for advice

I am seeking valuable insights from a seasoned professionals like yourself, with regards to my aspirations. To provide some context, a few years ago, I successfully purchased and managed a pizza establishment, which I subsequently made it profitable and sold within a span of three years. Following this, I ventured into the realm of Amazon FBA e-commerce and have been operating my business for the past three years. Currently, I am considering pursuing an MBA to further augment my business acumen, expand my network, and enhance my overall knowledge in the field, with the intention of eventually establishing a search fund.

While I recognize that I am still some distance away from commencing my search fund endeavor, I am eager to learn about the most effective approach to undertaking a company search. Would you recommend focusing on a particular industry based on my existing expertise, or would it be advisable to maintain a broader approach? Moreover, if you suggest concentrating on a specific industry, I would greatly appreciate your guidance on which industry to target.

Your insights on this matter would be immensely valued and appreciated.
