Jon's Close-to-Perfect Mojitos

I used this recipe last night and it got good results:

Place 5 fresh mint leaves in the bottom of a 16 oz. glass. 
Add 3 tsp. of sugar. Muddle the leaves and sugar together (about 10 times, you don't want to overdo it and start tearing the leaves). 
Squeeze in the juice from half a lime. 
Add 2 shots of clear rum. 
Add crushed ice (about 3/4 the way to the top). 
Fill the rest of the glass with club soda and stir to mix everything together.
If desired, garnish with a sprig of mint or a lime wedge.

Enjoy!
