Hey there.
If you're reading this post, clearly you've come here either out of curiosity or a need for information. Whichever it is, I hope this post suffices.
First things first, UI/UX is NOT an easy way to get into tech, contrary to social media opinions. Especially if you don't have some form of creativity, problem solving, writing or documentation experience before. It can be learned with enough practice, but that is with strong determination and consistency.
So you've finally decided to get into UI/UX Design or Product Design (Both terms can be used interchangeably, although Product Design is more encompassing), perhaps because you need a change of career, you've heard it is the trending thing in tech or because there is money in it. There's no right or wrong reason for getting into UI/UX Design if you ask me. But let's start off with these questions.
Whatever answer you provide here is going to be the main motivation you'll need throughout the course of your career and it might change from time to time. But the day you run out of this motivation, there might be a lack of focus or clarity.
So really ask yourself, why do you want to be a designer and let that be your guide.
One thing being a UI/UX designer will do to you is test you in various ways. Understanding your strengths and weaknesses will make it easy to navigate your work process. If you're not so good at carrying out research, but better at creating visuals, it might be easier for you to solely be a UI designer. Some people are good at designing for mobile while others are better at web.
Let me be honest with you, you need not know all these things. But the ones you do know, be so good at it that you can deliver excellently whenever you have to.
Simply put, get ready to leverage on your strengths and work on your weaknesses.
