The “five more” rule is a very simple, but effective, aid to concentration…
Whenever you feel like quitting – just do five more – five more minutes, five more exercises, five more pages, five more sums, five more verbs – and build on it.
The “five more” rule is effective because it pushes you beyond the point of frustration and helps build mental endurance. It’s also a form of training as well as being a way of getting something accomplished.
The “five more” rule is a manageable amount and can be built on. It creates its own reward so it’s satisfying, and it’s a way of sustaining concentration.
Concentration is an act of endless practice; the occasional effort that becomes a habit.
Give it a go, and see how much more you can achieve.
