Yes. The answer here might surprise some, but the Rising Force novel clearly shows that Obi-Wan wasn't considered naturally strong with the Force (unlike Anakin, for example). Qui-Gon had to forcefully insist that he be even trained as a Jedi. What Obi-Wan lacked in natural ability, he more than made up for in his devotion to study, meditation, and his resultant understanding of the Force. Coming to a knowledge of the Force in this way took much more effort than most Jedi. Still, it left Obi-Wan in a considerably advantageous position. With Qui-Gon's help, he had taught himself the ultimate form of discipline, self-restraint. With this under his belt, he would be able to master all sorts of new Force skills in the future - most importantly, how to become one with the Force.
