Quitting a full-time and permanent job is not easy.

• I secured a permanent government job as a scientist after graduating with a PhD from the Indian Institute of Technology, Bombay.

• It was an R&D position in a Defence Research and Development Organization (DRDO) Laboratory.

• The job involved innovating and developing techniques and devices in the domains of optics, photonics, optoelectronics, and electronics.

• I was dissatisfied with the work culture and administrative bureaucracy.

• I tried all possibilities to continue with my vision of research and innovation.

I took a couple of years' leave from my DRDO job and went to work at The University of Electro-Communications, Tokyo, Japan, on a Japanese Government MEXT Scholarship.

• After grinding for eleven long years in DRDO, I decided to quit.

• Quitting a permanent job with decent perks, an assured pension, and other annual benefits, such as a provident fund, etc., is not easy.

But I decided to quit DRDO to pursue my vision and passion.

But I haven't given up on my ideas of pursuing research, learning, and teaching.

• I love to read.

• I love to write.

• I love to listen to music.

• Sometimes I love to create videos.

• I like to innovate.

• I like to research.

I love to be with the students and faculty members.

• I love teaching.

• I like to learn new things.

• I love connecting with like-minded people, online and offline.

I have not quit my ideas of positive activities for self-development, professional and personal.

I have continued to pursue my growth ideas.

Afterwards, I joined academia, taught STEM, and pursued research.

• After quitting a permanent job in government R&D, I joined academia as a professor of electronics and communication engineering, and taught at different engineering colleges and universities.

I continued pursuing research in the cross-disciplinary areas of optics, photonics, optoelectronics, and computer science.

• This is another chapter, and I will describe it in an upcoming article.

The main theme is how to continue in a growth mindset.

<> Wait for the next article in this series.

Never give up your growth ideas.

• Quit all negativities and negative ideas.

• Quit toxic and unethical workplaces as early as possible.

• Disconnect from toxic acquaintances and toxic relatives.

Never give up your growth ideas.

• Pursue your passion.

Build resilience and grit.

• Create a community of positive humans.

Sometimes, broadcast your ideas.
