Do the maths before you conclude it is not enough. Forty five minutes five nights a week plus two hours on Saturday is a bit over five hours a week, which is more than 250 hours a year. That is not a small amount, and plenty of finished things have been built in less.
The reason it does not feel like progress is that six weeks of small sessions produces something invisible: a bit of structure, some decisions you no longer have to make. Keep a two line log of what you did each session and read it monthly. It stops the feeling that nothing is happening, because you can see that something was.
