Building a Bayis Neeman B'Yisrael Q&A - General advice for couples in Klei Kodesh

Question: Financial insecurity can be a big source of stress in a marriage. We are a klei kodesh/kollel/teaching couple living simply, but still struggling to make ends meet with children we have been blessed with in quick succession and the hope for more bshaah tova. What general advice would R’ Burg offer to a couple with big dreams of having big family iyh, the opportunity to channel our careers dedicated to the klal, but for whom the #s are just barely adding up. Thank you.
