Recommendations of the training years of Bruce Wayne

Fan of Batman comics and read so many different stories of the dark knight. However I can’t seem to find the lost years of Bruce Wayne of him from boy to man coming back to gotham. There are bits and pieces here and there of him training, but I am looking to read any story line in comics where its only about his training, could anyone help me with this for recommended reading?

Legends of the dark knight #52 & #53 Tao pt.1 & pt.2
A really great story from Batman’s early career, with flashbacks to his training in the far east.
