+Why do I want to learn ML?
+* ML brings better career opportunities. 
+* Have good prospect of higher compensation.
+* Applications in various domains,scope of ML is not narrow. 
+* Meet with other people working on interesting projects. 
+* Several job opportunities in ML. Demand>Supply at the moment.
+* Opportunity for me to excericse my analytical skills which I don't in my current job. 
+* Opportunity to create something that others may use or find useful.
+* Hopefully, help me escape wage slavery eventually.
