Each day you get another chance to make a difference, ease some pain, share some laughter, say you love someone, and be loved in return.
To pass up those opportunities is heinous -- because, eventually, our days stop coming. What remains then are the differences we made, the people whose lives are a little better because of what we did, and those who loved us and were loved by us.
Don't bet on "someday." Carpe diem.
