Very good advice...
I've been reading Seth Godin's blog for many years. He is a 'marketing' person, with a lot of good old fashioned common sense. I agree with most of what he writes - and he just did a longish post (for Seth Godin it was long). It was on Slack.
His two points in these unique times - if you find yourself unexpectedly with more free time than you had anticipated you should consider:
a) Continuing your education, learn something new. As you go to interview and look around, people will ask you what you've been doing with your time. If you can arrive at an interview with "I've been learning X in my free time" and be really excited about it - be able to converse about it, that'll be a really positive thing.
b) Participate - join the forums - become known. I've said that myself many times in the past.
So think about that if you find you have more time on your hands than you anticipated having... Not bad ideas. Even if you don't have a sudden abundance of free time - maybe find the time to do these two things..
