I agree with everything said.
First realize that it isn't difficult. You just haven't learnt it yet. Once you learn anything it become easy.
Second practice it as much as possible. Do it in front of mirrors and watch all of your angles. Take not of your bad ones and work out how to make them work for you.
Third, never give up.
I remember when I first read (probably shouldnt name the trick, but imagine its name is here

) It required only that I do a lateral palm and I couldnt do much of a regular palm. I tried for a few days and then moved on.
Funny enough, one day bought the Lennart Green series and when it came to the Snap Deal I spent a day practicing it. I mastered it within a couple of days and as a result ended up mastering lateral palming. So I mastered 2 things that seemed impossible for me, and in a very short amount of time.
I think my point is, they were only daunting tasks because I made them so. Dont get me wrong they aren't easy. But you sure as hell arent making them easier by thinking their harder.
