Keeping control on a snowboard

After many years of trial and error, I have found the 3 most important things to stay in control when snowboarding (and prevent people from bad-mouthing you) are:
1) Learn your dominant foot
This can be done one of two ways. If you are alone you option a; if you have company use option b
a. Sit down, stand up and take three steps.
b. Stand up and have someone push you (lightly)
Whatever foot you place out first is your dominate foot, this should be placed on the back end of the snowboard. AKA if you used your right foot first you are regular foot; if you used you left foot first, you are goofy foot. Many people begin snowboarding goofy foot (including me) because it feels more safe to have your dominate foot forward. It seems counterintuitive but your back foot is your dominate foot.
2) Keep your posture upright
It is often very easy when you start to lose control to lean low to the ground to stop. You actually gain more control by standing yourself upright and pushing down on the edge to create a 90 degree angle with the slope. Never lean low to the ground, you will lose control and wipe people out and they will get angry. Instead throw your shoulders back like your grandmom taught you and take control of your board.
3) Distribute your weight
At first, it seems right to place most of your weight on the back of the board because this is your dominate foot, but in reality you lose control by snowboarding this way. You should place about 70% of your weight on your front foot. The reason for this is it puts less weight on your dominant foot so you can swing the board around better and control your path.
