From time to time pressures of daily life just build up to a point of “almost-not-coping”. Either the demands one places on yourself or strains being applied in the workplace, add up to a place of joy-deprivation and dissatisfaction. In most cases it is not possible to change the environment in order to modify your contentment level.
Breaking through periods like these need a special type of survival skill. Shrink your area of focus till it falls within your personal space. Just for a while, like a tied-up sheep, graze only what is in your immediate reach.
Almost in an automated way, be busy with what is closest to you. Also with those things most beneficiary for yourself. This may sound selfish and self-centered, but this gives you time to ride through the turbulence, to recover your footing and to gain perspective.
Making your world a little smaller for a little while helps you to regain composure and reclaim your rhythm of happiness.
