Myth: UX and UI are the same thing

Reality: people tend to confuse the terms UX/UI when used together and think they are the same thing.  
When a company looks for a UX/UI Designer, it’s searching for a professional who knows how to deal with two areas.

UX (User Experience) is the process concerning product usability optimization, for this product to be functional and reach certain objectives, in a way the user has the best experience through your product.
The UI (User Interface) involves the processes concerning graphic design, appearance, presentation and product interactivity, i.e. the visual part. 

Myth: UX Design is new

Reality: People think that UX/UI Design is brand new and something that is focused on digital products only. Actually, it’s not.
The term User Experience was coined by Donald Norman in 1990 approximately. Norman, an engineer that used to be vicepresident at Apple, detected the need of thinking thoroughly about the way the the user interacts with devices.

Myth: The UX/UI work is for the client

Reality: A UX/UI Designer works and creates for their users, not the client. The client may have their requirements and preferences, but a UX/UI Designer always has to consider who will actually use their designs. As a UX/UI Designer, you have to put yourself in their shoes and think what/how they would **think** and **act**.

Myth: For UX/UI, you have to follow a strict scheme

Reality: Don’t forget that Design is the art of solving things in creative ways. So, a designer must be a creative person. If you follow a strict scheme, you may fall into monotony and the ideas won’t come up. Don’t be scared of thinking outside the box. Plus, everybody has a different way to work and solve things.
There are a lot of ways to represent the same idea, so don’t be afraid of taking your time to try new things.

Myth: For working as a UX/UI, you only have to know how to use the softwares of UX/UI prototyping

Reality: Yes, I mean, if you know how to use UX/UI prototyping software, you are ready to design a project. But, it’d be way better and would open so many doors if you expanded to other software and skills: After Effects, for animations of logos, loaders, illustrations, texts – Illustrator, for making your own illustrations – Blender, for 3D graphics. And, of course, programming coding: HTML, CSS, JavaScript…
And I’m not saying this for you just to make your CV richer and impress the company you want to work for. I’m saying this is important for you because, in this way, your ideas can go further and you have less limits when designing if you take care of almost everything. Even if you’re not programming in your project, knowing the languages would help you follow the project in more detail and get a better feedback between you and the developers.

Myth: As a UX/UI designer, you have to follow trends

Reality: It depends. Before following a trend you have to be honest and ask yourself: Is it worth it? Is it really going to fix my design problems and requirements?
Trends are cool and they are useful sometimes, but not always. Maybe that trend can help you improve the user’s experience through the product. But the trend rules may go against the UX, so you have to be careful.
Besides, you may have clients who are not going to refresh their platform design for at least 5/10 years, so don’t get carried away by trends because in 1 year it’ll grow old.

Conclutions

In short, UX Design is a giant world with many doors to open and discover, so you will never get bored. My advice is to always be open to learning new things and understand that UX Design is something that changes and is constantly updated, so you always have to be aware and predisposed.
