About 24 years ago, when I sat for my entrance examination to high school, I was asked to work out the following problem:
"A snail crawls 2 metres up a 5-metre-high wall during the day, but at night, while sleeping, falls 1 metre down. On what day will the snail reach the top of the wall?"
God knows why this morning I woke up and remembered that snail, and thought "no matter how frustrating it may feel to get stuck (and even "fall backwards") so often, the snail is bound to reach the top sooner or later... So... I am certain to get to the "top of my thesis-wall" one day too. Maybe the snail couldn't see the top of the wall from his position, probably it'd never reached the top before and then had no idea of what it would take... but it persisted...
Back to working on the "Scope and Focus of Study" section... Up like the snail!!!!
