The long term
Many times you find yourself stuck in small schemes, short term thinking, that can disempower you of your true capabilities. Rejoicce for all the good comes in the long term, and all the good comes from the eternal. So build for this life as if you live forever, and do good as if you'll die tomorrow.
Plant seeds for they may last a thousands of years, as the act of planting is but a moment of your life.
Do for this life as if you live forever, do for the afterlife as if you die tomorrow. Imam Ali ibn abi Talib
