This is a short and sweet tip for any designer out there.
Be more organized with your designs.
Be able to use grids, proper alignments, rulers etc to properly compose whatever you are designing is of the utmost importance. We often rely too much on our eye to make these judgment calls. As good as some of our eyes are, being able to make pixel perfect decisions with grid lends itself to super well organized and balanced aesthetics.
This is super important in typography. Learning how to properly set tools is the foundation for learning and applying all other gestalt theories. I am still working on my typesetting skills myself and when they progress my eye for everything else increases and I make better choices with composition.
Design is quickly becoming integral to UX/UI. They need to learn how to work hand in hand. A flashy webpage or a slick product does not mean a lot if the user experience or interface is terrible. So designing with the user in mind is of the utmost importance.
