Culture is a vital aspect of any entrepreneurship venture as Oman has a culture of dhando vado, with the Shia Lawatiyahs and Hindu Banias from Kutch, however the inland tribes were not as mobile. Oman had a maritime empire before oil, and that spirit needs to be recovered. An effective way would be to tap talent within the trader castes aka Omani Lawatiyahs or Ajmis for entrepreneurship. Oman is not talent void.
Oman is the ideal renewable playing ground with ample free land, good port and road infrastructure, sun and talent not accounting for the strategic location.
