Many golf beginners give up just because they get frustrated about not being able to execute their swing. This should not happen because swing is doable for every one even for kids and seniors. The most common mistake of beginning golfers is that they try to give as much strength they can muster in the execution of their swing. This is not necessary because fluidity in motion and direction driven swing is what is necessary.
Its the execution of the concept that is the issue and not understanding of it as is the case with physics. If you have noticed, I said physics. This is because golf swing is all physics. You will need to follow certain anglings and mind your movement to create fluidity of motion and giving direction to your ball.
