What steps should I take next?

So I worked for this bank for about 2 years and built strong relationships with the retail management teams and higher ups, I was actively looking for a new job and they knew it but they wanted to keep me in the bank and knew I had slight knowledge of computers and such as I'd help resolve issues when they were brought up. They vouched for me for the help desk/desktop tech position and they took a chance on me, I have 0 tech job or IT experience, no schooling but as of right now they're paying for me to take my A+ and I want to obviously continue getting certs and since we're a small team I learn way more than a normal it tech would learn on site. I'm a year and some months in at this point and I plan on staying for a total of 3 to 4 years while I gain on job experience and certs. What should my next step be? I'm interested in network engineering or system administration. I just worry if the experience and certs is enough, I see people struggle getting the position I got by luck with degrees so it makes me question is a degree worth it at this point or am I doing what I need to be doing currently?
