I agree. If you read my thoughts under "sustainability", this is what I talk about.

"I love spending time with my customers and community and learning new things. I like teaching and enjoy writing. I also want my business to have meaningful social presence. There is tremendous scope for doing all this while making decent money ($100k-$200k per year). While technologies may change, I can adopt and continue to be passionate about data, analytics, visualization in future and share what I learn with my audience. This is more sustainable."

And this is what I am going to do
