Guide me How should I proceed further

I am working as Tech support in the vfx industry.

I got this job from naukri, by keeping a one year fake experience. Now I have 3.7 years of genuine experience with the same company.

Initially I learned by watching free courses and content.

I used to practice 18 hours a day. I got current by asking a simple linux commands, since the role is Tech junior with 6 lpa at 2023. Here my day to day activities are rebooting users linux machines and restarting pcoip server if users as logging issues, vpn login issues, password reset, I can say just 20 % linux stuff. Now I became Tech shift Lead. With 8lpa in same company. But nothing here to learn and grow as well . Now I am in dilemma, what should I do next..

I can give my self Linux basics – 100%

Advance – 60 % like lack at DHCP DNS Network related troubleshoot.

Shell scripting 50%

Note : all above I leaned as per my intrest not using in my day to day activities

I learned Ansible 45 %,

Git 99%

What should I learn what is the next step.

In my mind I want learn

Grafana

Docker

Kubernetes

Cloud

Python scripting

HA proxy

Proxy servers

Like so many things running in my mind but not sure where to start, what should start first

Your suggestion will change my career.
