I've started spending a lot of my lunch hours at Waterstones book store 5 minutes away from work.

I'll go there, pick up an interesting looking self-development or business book, & spend 30 or 40 minutes reading.

I check the contents & go direct to chapters & sections that are relevant to things that interest me or that I want to learn. Then read through as much as I can in the 30 or 40 minutes.

Sure, I obviously don't read the book in depth. But I pick up plenty of nuggets of info & little motivations & positive things.

It adds a further 2.5 to 3 hours of reading per week.
