How to get a mold teacher quickly? How to finish the apprentice career from the masters quickly?

Please help everyone in the mold industry?

I graduated from a junior college and worked as a fitter for two years. I was only a generalist, and I didn’t reach the level of a master. I felt that the masters would only let me punch holes, grind something with a grinder, and mill something with a milling machine, and I'm not allowed to touch with the matching mold. So I have resigned these few days, I feel so tired, confused, and lost my direction. I was extinguished with the enthusiasm of learning technology at the beginning. Now I want to develop in mold design or CNC programming. I just want to ask the great gods, which is better? How to get a teacher quickly? How to finish the apprentice career from the masters quickly? It's uncomfortable if you don't want to be such a half-hearted level !  How to get out quickly? I don't want to be so half level always of this technology, I am  very uncomfortable!
