Which way is the job market going and what skills should one build to be in demand a few years from now?
The closest to being an entrepreneur is to work a sales position that is paid solely on commission. If you don't sell- you don't get paid.
Sales is going to show you what people are really needing. It will give you insight in how to market to this need. How much people will be willing to pay for your service/product.
Being paid solely on commission will show you whether you have the tenacity and will to manage you finances, and stick to it and find solutions when things look bleak. It will test you to see if you think like an entrepreneur , or think like an employee. Can you handle risk or do you avoid it.
If you are afraid of being totally responsible for what you earn- how much you make is how much you're willing to hustle, then you might rethink being an entrepreneur .
