Looking for a change from PHP to Golang

I am currently working as a back-end PHP developer and I have 1.5 years of work experience in the Software Industry. I got allocated to a maintenance project in my company as I am a fresher(I couldn't demand for a better one as I am a fresher). Now, I feel like I need to change the technology and project.

So I have started self studying Go programming as I think it is the one which is a real good one to replace the existing ones. Anyone suggest some good ways to study go programming and also some really helpful exercises to work out on Go so that I can master Go programming.

Also suggest some other tech stack which I must acquire along with GO to find a better career path.
