I'm a top rated data analyst freelancer on upwork and i'm starting to feel uncertain about data analysis market. The thing is i feel it has such a small market in comparison to other freelancing fields and most jobs are low rates with crazy requirements on each job , demanding you to know every technique and technology which is rediculous. And you barely make it into good jobs that come once in 3 days

I'm here seeking for opinion and guidance from any fellow data analyst/scientist freelancers , should i stop using upwork and attempt to land clients worldwide, or just switch my field and learn something new , or i'm just worried a lot , please let me know.
