It seems that Toby sharing the common progression chord sheet in combination with @LievenDV 's so useful post
plus all links Lieven included there, are my lifeline when developing more discipline and patience with guitar.
Prior to being many weeks away from guitar, I was stuck with consolidating Grade 1 and learning to play and sing five songs by heart. While that developed quite nicely, my playing never sounded as good as I would have liked it to be. After reading Lieven’s post(s) I understand why. I often had been playing many hours per day on the weekends and during vacation time. But there have been way too many days when I have been to stressed and tired from work and wouldn’t touch my guitar at all. Easy with practicing habits like this that life came in the way, so to say, that my playing grew less and less until it stopped completely for weeks and weeks.
What I will try now is this:
For the rest of the month. I will reserve half an hour every morning before I have to go to work for practicing common chord progressions in G and C. The practicing sessions will include strumming in “Old faithful”, a 6:8 strumming pattern, a simple 6:8 fingerpicking pattern, a simple 4:4 fingerpicking pattern.
Especially the fingerpicking practicing minutes will motivate me to improve my fingerplacement, as well as hopefully induce more simultaneous chord changes, in addition I want to experiment with how lightly I can place my fingers on the strings and still having chords ring out clearly.
If this means discovering that I can change to the mini-F fast enough not to interrupt the rhythm of my 6:8 fingerpicking pattern, and if that means that in 10 or 15 % of the cases all strings of the mini-F even ring out nicely enough, as happened today. Then the added discipline will hopefully pay off in the long run 
Ah yes … I’ll try to add another 30 min practicing in the evenings after work, which will.then be reserved exclusively for practicing my 5 Grade 1 consolidation songs.
