Thanks grouchyOldGuy.

You bring up a few good points. I have noticed that since I had to break away from a task for a few weeks at a stretch (like my Haskell learning) coming back to it means spending a few more days revising what I had learned! I like your suggestion of writing things down to leverage other parts of your brain. I do some mind-mapping, but probably not enough.

About me, I live by myself, so if I don't want to be disturbed, I put the phone off, and I am in complete solitude. I do have a full time job, which does take up a (fixed) number of hours everyday.

Thanks for the advice.
