Fixing the One Thing

It has been said to focus is to make the main thing the main thing. What is the one thing in your life that is the main thing? Found it, focus on it.
The preacher was long-winded. His congregation knows it and had mentioned it to him. And now the new pastor in his church does the same thing. The feedback couldn't be more clear. So why not fix it?
A youth pastor had received complaints that he is out of touch with his youths. Many young people have stopped coming. Some even shared it with their parents who told their senior pastor. Everyone knows, so why not fix it?
A church elder is the lead elder in his congregation. But he is not well-liked. He was elected mainly because he was influential and powerful. People know he's not a good spiritual leader, so why not fix it?
If your "one thing" in whatever you do is the key part of what you do, wouldn't you change to fix the problem if there's one?
However, if it is the lack of will or ignorance that is holding you back, it's time something intentional be done to solve the problem. The long-winded preacher can learn to cut his time down in his preaching by being more focused. The youth pastor can benefit from some reflection and learning through attending some youth events or meeting with other youth pastors. The elder can be told his condition and be encouraged to allow God to use him in appropriate ways.
In all these, it just takes a commitment, not just waiting for a miracle.
If something's not right, why not fix it? Particularly if it is the One Thing?
