Your idea of dropping a drop of solder just will not work - the basis of
soldering is that you have to heat up both items to be soldered together to
a temperature sufficient to melt the solder. Solder will not bond to a
metal colder than its melting point, you will get what is called a dry
joint or cold solder joint. You will be able to just scrape the solder off
with your finger. You need to heat up both the component and the PCB solder
pad simultaneously with the iron, then apply solder and let it melt over the
entire joint area, then remove the iron and allow to cool.

Yep, that's the way it's done and why.
