Constant Attention

Two things are considered as difficult as the parting of the Reed sea: livelihood and marriage.

Rav Yaakov Kamenetzky develops the point: livelihood needs constant attention and care. One cannot give sporadic attention to his business or job and expect to have a living Parnossah.
A person needs to come up with new creative ways to keep and earn his living -- new avenues of business, new markets etc. In a job one has to maintain one’s status and remain current with new trends and developments in one’s field or profession.
So too by zivugim (marriage as well, not just matchmaking) and livelihood. There can be no coasting. It must be constantly nurtured, expanded, and maintained. We have to constantly make calls and research potential names, expanding our search to other countries, if necessary. Try other methods and any avenue available in order to be successful.
