The more degree of loft on a golf club, the easier it is to hit. Not only is it easier to make consistent contact, but there is also a greater likelihood of the ball going straight. For these reasons, a golfer should learn to hit more lofted clubs before they try to learn how to hit less lofted clubs.
Why are the more lofted clubs easier to hit? Number one, the more loft on the clubface, the more backspin will be imparted on the ball. As loft decreases, backspin gives way to sidespin. The sand wedge (lob wedge) has the most loft and therefore creates the highest amount of backspin. It is very difficult to put sidespin on a ball (drawing or fading the ball) with a sand wedge even if the golfer tries to on purpose.
Additionally, shorter clubs are easier to hit, and the more loft on a club the shorter the shaft. Shorter clubs put us closer to the ball at address, allowing us to swing the club on a steep plane (more 'in front' of our body than 'around the back' of it). The club will also swing on a smaller arc which makes the timing easier.
The driver (the least lofted club) is generally the hardest club to hit because if the timing is not perfect (clubface must contact the ball completely square to the target line), a great deal of sidespin will be imparted on the ball and cause it to hook or slice uncontrollably. During a driver swing, the clubhead must travel on the biggest arc of all the clubs, and on the flattest plane of all the clubs. Getting the shaft on the correct plane on the downswing with the driver is a difficult task for most beginning golfers to achieve. They will generally get it too steep on the way down and pull or slice the ball.
While it's true that modern day drivers are easier to hit than they used to be (due to a larger clubface/ sweet spot), mastering the drive can take a lot of time, so it's something a golfer should work towards patiently. It's better to hit an eight iron to the fairway than hitting a driver out of bounds or into a hazard. Get comfortable hitting the more lofted clubs then work through the other clubs one by one, decreasing loft as the swing improves.
