You have reached the end. Two things remain: an honest summary of what this program offers and the parts that are most useful to keep.

First, the honest summary. The research presented in Unit 1 is well established and traceable. The techniques in Unit 2 come from a tested program, presented here without its diagnostic framework.

What has not been tested is this particular combination of techniques as a complete digital program. Treat what you have read as carefully sourced rather than as a proven package.

Lesson 13 remains one of the most important parts of the program. If concentration has been a persistent difficulty rather than a recent one, another focus technique may not be the most useful next step. Understanding what is affecting your attention may matter more.

For many people, that means using another program in this app or speaking with a professional. This is not a detour. Attention is influenced by workload, sleep, worry and mood. Addressing these problems may be what allows concentration to return.

What should you keep from this program? Most of the techniques can be used only when they are relevant. Two changes are especially worth maintaining:

• One protected hour during your peak. If you keep only one thing, consider keeping this. Once it is in your calendar, it requires less effort to maintain. It can also survive a difficult week because it changes where the work happens instead of asking you to produce more attention.
• The changes to your environment. Turn off notifications, keep your phone out of reach and use one active window whenever possible. These changes are made once and continue to help on the days when your attention is already depleted.

Use the remaining techniques when the situation calls for them. The starting approaches are for a task you have been avoiding. The estimate log is useful when your planning becomes unrealistic again. The guidance about breaks matters most during demanding periods.

None of these needs to become a permanent daily practice. Turning every useful tool into an obligation can create a system that produces guilt instead of support.

It also helps to recognise how the habits may begin to fade. Your protected hour is given away for a couple of weeks and never returns. Notifications are switched on for one urgent situation and remain on. You stop writing the plan the evening before and begin building the day from your inbox at 9:30am.

These are usually the first signs that the old pattern is returning. Noticing them early makes it easier to restore the structure without restarting the whole program.

If, one month from now, the only thing still in place is one protected hour during your best time of day, that is already valuable. Once it is in the calendar, it asks very little from you and can remain available on the days when the other techniques are harder to use.
