I've always liked "Mens sana in corpore sano" and it's even better that they have almost the literal same saying Arabic (which I speak) that goes "العقل السليم في الجسم السليم"
> I'm thinking of ditching my iPhone for a flip phone.
That reminds me of my college days back in 2011 when I decided to go for a flip phone instead of a smartphone. Most of my friends thought I was peculiar for my insisting I use one and to do this day I still have that same flip phone, but not in use; just as a memento... sort of.
At the time, I wasn't really thinking about how my attention was a valuable resource or that most smartphone apps were major distractions. I just simply didn't like how inundated with features smartphones were. I always thought my laptop as my primary place of "getting-work-done" and my gaming laptop for entertainment (i.e. helluva lot of StarCraft II) and to have a phone that competed with that, but far worse, never sat well with me.
Looking back, I'm glad I did that and wish I could continue with a phone that could only text/call.
Be that as it may, the OP never mentioned where he is working from. As you probably already know, labor laws and business culture differ depending on where you live.
For instance, I live and work in Saudi Arabia right now, and there is a lot of red tape around firing Saudis in the workplace--even wages are partly determined by your country of origin.
I remember hearing about starfighters.io sometime back and putting on my ever-growing tab of "Visit on freetime", but now it's--in all likelihood--gone forever.
