MODS -- would you please change the title of this thread? It's about Vodka Martinis, not Martinis.....
Chill the glass. Put the vermouth in the shaker. Put the gin (or vodka) in the shaker and let it chill while you spear a couple, few olives from the jar that has been in the fridge. Put the olives in the martini glass. Shake the SH!T out of the contents of the shaker and pour into the glass.
Very important part. Hold the full glass up to the setting sun to observe the ice crystals refracting the sun's rays and toast to another day. ENJOY.
