How hard is it?

How hard is it to get a job without connections or a referral? I graduated three years ago and got an entry level salary gig somewhere I did not even have the “qualifications” just because someone knew me there. Although it has helped survive I think I’m not growing as a person and even If I work there for 10 years I will still be at the same spot. I’m thinking of leaving and applying elsewhere but I have been hearing stories that huku nje hakuna kazi. So how hard is it to get a job for a person with zero experience?
