With great difficulty and often at the expense of sleep, leisure and other activities. I unfortunately don’t have a set process and doing exercises and making progress seems slow because it is slow!!

I love videos and articles these are the most efficient way to absorb essential concepts provided they are written/released either by experts or great teachers.

Books are good references and great resources for problems/exercises but working through an entire book can be a chore.

The only thing I can claim to be good at is that I am persistent and I come back again and again either to same material or similar material for deeper understanding.

Now part me still wishes I should have continued on in academia after my PhD, because there I had license to read.
