Be willing to take calculated risks that have a considerable chance at failing when it comes to your own education & development. View it as a dare, and if it backfires, continue to see it as a dare. Plan well, test often, and keep moving, as the industry is never static.
When I made the decision to leave my first professional SEO job, I took an aggressive stance and applied at an agency that I felt like I was unready for. My then-employer, a large Digital Marketing firm, took care of a freelance-local-guy-turned-professional like me, and I'm forever grateful, but after 18 months of SEO meetups, conferences, voluntary OT and projects, I felt like I was ready for a big step up.
Check that - I wasn't "ready", but I was ready to dive deeper. It just felt right, and I didn't know what it would take, but when I saw the job posting, I applied. I contacted the CEO directly, I told them the truth about my relative experience, and I got lucky and was hired.
I worked hard. H-A-R-D. I made it a passion project to exceed my employer's expectations. I studied daily, I dedicated myself to learning new tools, deep-end dives into Excel, mastering parts of SEO that used to scare me senseless (looking at you, URL Parameters), and within a few months, I was let go from the agency. The combination of not being a great fit and my rapid-but-not-rapid-enough education seemed to be the cause, and I was deflated. The CEO reached out, offered to give me a hand in finding a new job, and while I didn't need it, I was grateful and will always be. But I was at a mental bottom - all of that effort, and for what? I didn't have much of a pay raise and my taking the job was solely about learning how the top-level minds operate, and I kept asking myself as I applied for new jobs on LinkedIn, "What did I get out of it?"
Well, I ended up getting more education and experience in 4 months than I had received in the previous 12. All of that effort and work in trying to be better at what I do didn't just go out the window once I faced rejection. My first interviews were a breeze; I could explain not just that backlinks were good, but the theory behind links being seen as a "vote", all the way down to the logical theory, and when I landed back on my feet in my next role, I was ready for bigger responsibilities, and I had the confidence and the technical mindset for a solid foundation that I hadn't had in a very long time.
Long story short: Be hungry, take on projects, see where your limits are, and make it fun so you never have to work a day in your life.
