In terms of a Grape Vine, in order to increase the quality of the product, you have to prune the foliage, buds, shoots and spurs. Up to 85% of the foliage is usually pruned from the previous season.
Your career, in this respect, should be pruned as well. Are you spending too much time in areas that are watering down your career i.e. product? To hone our skills and become really great ( not just good ) at something, you have to focus a majority of your energy in that area. You can't become an expert at Web Development, Graphic Design or even Sales if your focus is scattered. Spend some time each year to prune areas of your career that aren't allowing you to be great.
