What finishing is actually for
Worth being clear about before the middle arrives.
People enrol for specific reasons: a required credential, a change of field, a promotion that needs a qualification, or something unfinished from earlier in life. The reason matters most in the middle period, when the immediate work is dull and the destination is what sustains it.
A reason that will not sustain a year of evenings is worth identifying early. Vague self-improvement is a poor engine for something this demanding, and there is no shame in concluding that the cost is not worth it before spending the money.
Where the reason is a career outcome, it is worth checking it is real. Whether the qualification actually opens the intended door, and whether employers in the field regard it as sufficient, is checkable in advance by asking people already doing the work.
The people who describe it as worth it afterwards mention two things with unusual consistency: the door it opened, and having proved to themselves that they could do it while everything else was going on. The second is not a small thing.
It is worth adding that the transferable habit is often more durable than the qualification. People who complete a course while working frequently report that the arrangement they built, an hour early each morning, a protected evening, continued afterwards and was applied to something else. That is not usually what anybody enrolled for and it is regularly what they value most.
