The Talmud cites a Mishnah that the tools used in Temple all had a second and third backup. This was to ensure that if one became ritually impure the holy service could go on without interruption. This was a danger during festivals, when the Temple was packed with pilgrims and with priests who did not ordinarily serve and may be less careful with purity.
The Gemara discusses if the table of show bread (lehem haPanim) that was in the Temple could become impure. During festivals the priests would take out the table to display to everyone the miracle that it was still hot and fresh a week after it was baked. Otherwise the table with the bread had to be constantly in the Temple, due to Exodus 25:30.
The display of fresh bread was to help the nation understand the consistency of God’s love for the people. Human love starts with intense passion and tends to wane over time. The hormones that produce the initial state of obsessive love decrease. Only God is perfectly consistent, and His commitment to us does not wane. Just as the bread retained freshness so God retains love for us.
These aspects of the Temple remind modern men of a couple of important traits. First, have a backup plan and extra equipment. If your business relies on one item or vehicle then you better plan on how to get two. Make a continuity of operations plan so you can keep on trucking.
This applies to your personal business as well. If you go to the gym and find it closed, know what to do to get your workout in. If you made plans with someone and they stand you up, have something worthwhile to do instead.
We also learn the value of consistency. We cannot keep up emotional energy forever as God does. But when a man is able to maintain his excitement and energy in a relationship, this makes him appreciated and desired. This is not advice to make the relationship fun, that is a common trope which is not really helpful. Instead make yourself a fun and interesting person to be around. Others will naturally be drawn to you and they will put in the work to forge a relationship.
