How do we learn multiple technologies at once?

Sir,

Multiple Technologies like Cloud, DevOps, Data bases, Data Engineering, Deployment, etc… along with the core subjects like Python, Data Science, Machine Learning, Deep Learning, Version Control, Command Line etc… constitute the Full Stack of Data Science.

So, how do we learn all such multiple technologies at once??

Shud we try to learn them one after the other

Or

Multiple ones simultaneously??

Either ways I feel it’s gonna consume a lot of time…

So, can any you please suggest the most efficient strategy to learn them at a much faster pace & also retain them for long?

Truly appreciate the help.

Hi, Taking a project that includes bits and pieces of more number of technologies is the best way to go.

Thank you for the response Sir!!
