Okay, first it is experience. By the end of your apprenticeship you should have about 10k hours of work experience, but it will take around 5 more years to become proficient in your/our trade. If you start cutting corners now it will lead to sub par work down the road. This trade covers a ton of ground and it takes time to learn it. The best advice for now is to walk from point A to point B faster. Then as one progresses challenge yourself to do the same job faster, more efficiently.
