Well the news is not that bad the Sei will be more difficult than some other autos but easier than a Citroen C1s.
The clutch needs adjusting to allow it to have a reasonable service life. The adjustment wont make driving in traffic any easier for you.
If the clutch were on the way out it gets heavier or makes strange noises, the cable snaps or other parts in the linkage between the pedal and the clutch fail.
what you need to do is to not use the clutch e.g. when waiting for lights to change or for gap in traffic. It is not a good idea on any vehicle.
The more exact description of the problem is that that part of the release bearing is plastic and melts when it overheats so the release bearing turns into a milling machine and wears away the clutch spring.
My Sei made 65k miles with girly drivers at least one of which had L plates, so it is tolerant to a degree.
Id save up money and learn auto maintenance.
