Whether you're new to UX or a seasoned pro, there's always something new learn.
Hard-line "rules" can be difficult to apply to UX in a broad sense, because there's no blanket approach to solving UX problems.
Solutions stem from your users, your conversations and testing with them, and should be copy/pasted across projects.
There are, however, big learning opportunities from each project around best practice, the key thoughts which will point you in the right direction.
Here we have an evolving list of 101 tips for better UX, to make you think, make you ask the right questions, stay curious and do right by your users.
The internet is full of all kinds of lists of “7 rules to great UX” and whatnot. I never felt like they are enough. In a way they are because I like when you only have less than 10 rules. Its easier to obey them for sure. But if you’re just starting with UX and want to keep them as a guidebook to guide you through a rough start? Seven is not enough.
