If it’s a mistake to add the burden of the past to the weight of the present, it’s a still worse mistake to burden the present with the future. […] We are obliged to plan for the future and take thought for tomorrow. But we should do it without worrying, without the care that gnaws at the heart but doesn’t solve anything—and often prevents us from putting our hearts into what we have to do here and now. Hearts anxious about tomorrow can’t be open to the grace of the present moment.
from Interior Freedom, by Fr. Jacques Philippe p.87
