Typically, the more careful attention and observation that you pay to things the longer they last. Whether it be a car, clothes, or a marriage.
Some things in life may not be worth your careful attention and observation, others cannot do without it. It is good to determine how much careful attention you will pay to your phone charger and the dishwasher, as well as for all of your relationships.
The exceptions are that some things, regardless of how much careful attention is paid, are so severely broken and are acted upon by forces that are broken such that the utmost careful attention will not permit them to last.
“We must pay more careful attention, therefore, to what we have heard, so that we do not drift away.” – Hebrews 2:1
“Pay careful attention to yourselves and to all the flock, in which the Holy Spirit has made you overseers, to care for the church of God, which he obtained with his own blood.” – Acts 20:28
