Not for me and no. I can only do it because I had help. Normally, humans can only hold the power of one element at a time. Air and Water were about as easy to learn for me as Fire was. I managed to master them in less than a year and it took me almost a year to master Fire. Fire was just the first one I was granted. Earth I'm still struggling with. I can do it, but I can't do a lot of the fancier things with it that I can with the others.
