PizzaTacoCat312's journey

I'm just starting my job search after spending a decade at my previous company, and I'm feeling pretty discouraged. I keep looking at job postings and thinking I'm underqualified for everything. I'm curious about how many of the required skills people typically have when they get hired. Is it common for applicants to only meet about 50-60% of the job requirements? Also, how can I tell if a skill listed is essential or just a nice-to-have? Any insights would really help me feel more confident as I navigate this process.
