Like everyone else said, it's easy for some, harder for others. But you'll get there eventually. And if it takes you longer to learn than your friends or family, don't worry about that. it doesn't mean you're inferior; no one will care once you know how to drive anyway.
It took me almost two years and probably 100+ lessons to learn how to drive. I always felt stupid because I knew people who passed with fewer lessons (and the national average is 27 or something) and passed first time. But it doesn't bother me now, because I've passed my test and can drive just as well as all those people who had much fewer lessons. And as my instructor would say, everyone can learn to drive. There is no one out there who will never be able to do it.
