How do you do tricks in snowboarding?

I think snowboarding is the greatest sport in the world but I have one question how do you get sooo good like do tricks ??? Is it like something that you just try and practice or do you have to be tought to do the tricks?
Im learing and every teacher has told me that im ready to ride alone on the mountain so I did and I would really like to know how to do a trick just one an easy one any advice im open for disscussion...

Hi,

The easiest one is a 50/50 grind.

STEP 1: Look for a good place to grind. Find a Snowboarding Rail that is not too high so you will be able to execute an Ollie with ease.

STEP 2: Approach is very crucial in doing a 50/50 Grind, as this will ensure that your board will stay flat and straight while on the rail. Ride down the rail, keeping speed under control.

STEP 3: Have a good take-off so you will stay balanced and in control. Crouch slightly and make a small Ollie to reach the rail, with your board completely on its surface.

STEP 4: Simply grind like you would if you are just on snow. Keep your board parallel to the Snowboarding Rail. Maintain your balance and just go with the grind.

STEP 5: To get off, make a small Ollie as you reach the end of the rail. Have perfect timing to avoid an early exit.

STEP 6: Land with both feet and then ride away.

prkswllflwr is right, thats a really easy trick. But whats even easier is doing that on a box...its almost easier than riding...you pretty much just ride up to hte box and ride down it...it may be kinked or flat(don't try a C-box). Its not hard at all. Also, you may just want to try a 180..you don't even need a jump to do it...I think 180s are pretty much self explanitory, goodluck!
