During lockdown How to stay productive at home

Yes, there are so many ways to stay productive regardless of what situations are happening in outside of our environment. Without doing anything is wasting your time. Just hearing from others might not give you experiences.
Unless you do with your own effort, nothing will remain in you but just hearsay.

Cooking or Baking 
So, let's start thinking from this question "What can make you enjoyed?". You might answer that "I love eating". Wow that's not simple answer. This can be the first step of becoming a good chef or baker with big purposes. 

Pictures or Video clips
You have camera but you forgot to use it because you were busy the whole time with your professional jobs. I think it would be better if you search it and hold with your hands again to capture the way your family stays at home. Try with the simple pictures and video clips. Later on the creating skills will be upgraded by learning new methods of using camera.

Dancing or Exercises 
When everyone was dancing but you might had been felt embarrassed in front of your coworkers, childhood friends and your love ones. See this stay home period as opportunity to teach by yourself. Beside it's time to learn to reduce from gaining weight by doing exercises regularly. 

Polish working skills
Weak at using excel software, communication, calculating, budget management, leadership, or still try to get used to with power point ? Come on.. why don't you fill up in your weak to be strength. 

Teaching
Learners are waiting for the people who can bring knowledge and language teaching. Use online as a carrier to students. That's also one of the ideas to get income during pandemic. If you don't have teaching experiences, tell your family to listen when you practice and ask for feedback.   

Conclusion
Don't be discouraged, be enjoyed even the situation didn't give favor but you can give favor to other people.
