In my first few years, I included some type of mod on the original circuit (extra switch, knob, change clipping diodes, etc) on every single pedal I built. That's a way to learn a bit at a time as you go.
The Electrosmash Tube Screamer article was very helpful for me. The non-inverting op amp block comes up so frequently, often with bass cut, so it's helpful to be really familiar with that.
