The mistake most people make is not having the right size drill bit for the right size screw, in wood if you remember to use a , 2.5 mm drill bit for a no6 screw and a 3mm bit for a no8 screw, you won’t go wrong because it pilots a hole smaller than the screw, and it will grip, and in masonry it’s a 6mm hole for a no6 rawlplug (usually red) and a 7mm hole for a no7 plug (usually brown) 🙂
