Once in a while
Take a small break from your routine.
Sit quietly in a corner.
Go through your plans for the future.
Review your journey until now.
Judge where you are placed currently.
Reset your plans if need be.
A blunt axe cannot cut a tree
Better to take some time out to sharpen the axe and start afresh
The time taken to sharpen your axe is its best possible usage of it and not wastage.
