First of all, everything is difficult at the beginning. You can find a small company and practice. Small companies look at people (your personality and plasticity) more. Large companies generally look at works directly because of fierce competition. If you submit your resume online, you won't have an interview. But based on your question, I can analyze that you are a calculating person, at least you are thinking about the problem and looking for a solution.
Second, you should change your way of thinking about advertising or design. People live in this noisy environment where advertisements fly everywhere every day. In fact, if you take the subway or bus, hundreds of advertisements have flown by you. Of course, small posters also count, and the small posters of "accreditation" also convey information, which is of course an advertisement.
When you first mention creativity, even if you have a shocking idea, it is a moment of surprise. People often recall your creativity, but forget the essence of the product behind it. For example, if you design a luggage advertisement, people will remember your creativity, but they don't know what brand it is. This will hurt customers. As a designer, you don't want this to happen!
Third, designers are not a profession that racked their brains. This point was distorted when we first set up the campus. You should fully consider the demands of customers and the highlights of products from the customer's point of view, seize this key point, enlarge it and make it shine! This is what you should do. Different industries and customers have different demands. For example, if you make a product manual for heavy industry, you must first understand his products and product characteristics. If there are photos of assembly line production, you should know the general flow of assembly line. For another example, if you want to make packaging for a milk powder manufacturer, you should consider from the perspective of a mother how to arouse her love for her children. You should love her children more than a mother! Then you have caught a key point, and we assume that "practical safety" is an idea! You can give full play to the image of mother as the patron saint and defender of children, and create a great image full of motherhood to melt her heart instantly. You know, if consumers pay the bill, you must know more about your products that serve customers than they do, and you should also consider them more comprehensively than consumers. People's desire to buy is only a few seconds. If they can't catch it, the design money will be wasted.
The development direction of graphic design is diversified. An operating software interface on ipad also belongs to the category of graphic design, which was put forward by people. Nowadays, people design according to considerable aesthetic laws, and few people can innovate. This kind of innovation is completely different from creativity. It would be great if we could enrich the content and expand the scope of graphic design.
Everyone's mind is a small universe. This is my own summary, because through this skinny, you don't know whether the other person's skull is sunny or dark. Of course, so is your brain. I compare the human head to a country with different geological characteristics, different weather changes and different levels of economic development. It's like every different unit of your brain makes up your different memories, with different emotional changes and different strengths. Why not tap the brain cells that are not activated in your own mind and explore more directions about design? Your capital is your brain.
Design needs to live with your heart, get something from it, and it is called design after being reprocessed by your brain.
Design practice is completely different from other things learned in school (except the basics and software applications). Work lets you know whether this industry is suitable for you. Come on!
