INTP:
You could get a dupont crimper kit, so the only real soldering you have to do is soldering headers onto things that don't already come with them attached.
Hm, I have never been able to get the time it takes to crimp connectors down to a reasonable length of time, even with the guide - it's still faster for me to cut pre-crimped dupont line and solder the ends onto the wires vs crimping a pin onto it, and I get better yield, and they always fit the housings (my own-crimped ones dont always fit well)
