A problem I often face hand soldering surface mount components is keeping them in the correct position while soldering the first end. The surface tension of the solder invariably moves the component. When using paste and an oven the surface tension is the same on both ends and pulls the component into position. Solder paste and hot air works similarly but it is easy to blow the component away.
One solution is to tin the pad and the end of the component first and then use tweezers to hold the component on the pad while applying the soldering iron to the tinned end. However that requires a steady hand and today, after having two strong cups of coffee, my hands are far from steady!
Some time ago I bought a PCBite probing kit from Elektor. This consists of a steel base, four magnetic clamping posts to hold a PCB and four sharp tip probes with magnetic bases and flexible swan necks intended for making measurements. It works well for its intended purpose although I think the flexible necks would be better if they were stiffer.
