If you have spare time, do it. Scrolling through TikTok / Instagram is a waste of time (which I still do). I need to remind myself not to lose my little grey cells and lock in. Work is long so balance hours of sleep at the cost of more development satisfaction on quantity / quality
Make it darker! My eyeballs are saved from being flashbanged every time I open this site!
Details are important, but how far do you go? Depends, I like simple things (like myself) so prefer an easy aesthetically pleasing minimalistic design.
Smaller details (like these highlighted box borders) can give off a unique feel to the website making it stand out, so long as not too much is added and is not intrusive. Additionally, interactive elements can be used to engage the user and keep them on your website for longer! Yes, making these text boxes clickable is one of my ideas :D
As I love layouts, I enjoy having everything organised properly (despite sucking at doing this in real life) which can be applied to either folders or writing code. EXAMPLE: Use a tree structure for folders and put items in groups if you can, this will make developing quicker and easier for you to identify parts you want to improve / work on.
Writing... and a lot of it.
