I have written in the past about little blocks and building big achievements out of small tasks. This technique breaks down tasks that are seemingly overwhelming and helps keep the momentum going. It also has another use and that is the reduction of fatigue.
Simply put, when we set out on the long road to change our situation, it is easy to get tired, it is easy to want to rest. When we walk this long road and there is no sign of an end it can seem impossible to go on. If we see that journey in sections, in little blocks, it becomes easier, progress can be measured and accomplishment can be felt.
It is the little blocks, the doing just this bit just right now that makes big things happen.
