What’s the most common mistake among beginner programmers?

The problem lies in focusing. Almost every beginner I've talked to has this kind of issue.

They want to learn EVERYTHING in very short period of time.

That's why, nowadays, we face a HUGE problem with professionalism. Many people don't want to specialize in one field; they don't want to focus on one thing.

They think that simply learning something automatically makes them good programmers. Then, these individuals are fucking surprised when they struggle to find a job.

ONLY AFTER BECOMING A REAL PROFESSIONAL IN A SPECIFIC FIELD YOU’LL RECEIVE TONS OF OFFERS.
