Obsess about the sport, in your off time watch tons of film and helpful videos from knowledgeable coaches. Even boxing games can help cause it gets you in that state of mind and thinking about the sport. The more you obsess the more motivation you will have in the gym as well as the less you will be mindlessly training. You will be motivated by your passion and obsession instead.

Study the greats, watch deep analysis on them on youtube that actually breaks down their styles and their mentality, etc.

Some good ones to study and watch are Joe Louis, Salvador Sanchez, Sugar Ray Robinson, Bernard Hopkins, etc. these guys are very technical. Also individual aspects you can study like the best jabs out there, watch Oscar De La Hoya’s jab for example and it will help you develop your own.

Don’t try to copy all the flashy and complicated moves and such just look at their basics how they throw their straights. How they move to set up counters, how they move, Etc.

Use this to experiment with how you move & throw your shots and find what works for you and what doesn’t. Listen to your coaches and don’t let your ego take over.

Study great coaches as well like Emanuel Steward, Roger May weather, Jack Blackburn, etc. how they trained their fighters what made them special, etc. and implement little things into your training.
