For me, the trinity of development as a solo developer seems to be:
1. Writing code while using as many useful libraries and tools as possible to avoid recreating wheels
2. Continuous integration set up early on to handle the menial work and to let me concentrate on 1.
3. Constantly evaluating and researching what technology is available and newly appearing to give me an edge, because having an edge is never a bad thing in this field.
Agree with some of what OP said, especially with methodologies become hindrances and HA tools becoming points of failure.
