This is generic advice given to young people in Africa.
The impression being that you need a job first to become an entrepreneur.
The dynamics in some African countries is complex. You will struggle to get a job and when you get one you struggle to survive.
There’s nothing wrong with getting a job if you can find one. But at the same time don’t put the pursuit of your dreams on hold because you dont have a job.
There is no right method. Some have done it without getting jobs whilst some do it whilst working full-time jobs
Keep pushing and use every opportunity you have to move a step closer to the dream.
