Snowboarding is nothing like skateboarding although we know of some instructors who still throw the skateboard analogy out there. Skateboarders tend to weight their back feet. In snowboarding, you weight your front foot to start down the fall line and initiate a turn, just like in surfing when you learn to load the nose of the board at the top of a wave. Attitude and relaxation is half the battle. Positive attitude always succeeds because it will relax you.
Tension is the enemy of natural movements.
Stand on your heelside edge of the board when buckling in. It's a lot easier and will save you the embarrassment of achieving your first fall while mounting a stationary board. Unless you are using a step-in binding, you will have to leave your back foot unhooked when negotiating chair lifts. Having the board dangling from one leg is a pain, literally. You can alleviate some of the stress by hooking the free foot under the bottom of the board to give your front leg a rest.
