Success entrepreneur working on business not in business. Entrepreneur is master of time management and job delegation.
Some business built not by entrepreneur (pesonality), but by technician who suffering from past company, willing to be own boss, believe that he/she can do thing better. The businsess may be run, but the owner's technician personality will make the business keep small and full of struggle.
