Not moving more often to new challenges. My cycle tends to be 5-7 years in one position. You get stale and technology advances tend to not keep up with your workplace.

not leaving my cushion job sooner. was not learning anything new and being pushed to becoming a better developer

Comparing my coding skills to others and valuing myself (rates/salary) relative to where I see myself in that comparison - better = higher/worse = lower.

We all have different skill levels and different needs financially - it's more about applying what you know and making it valuable to you employer/client, when you do that you don't need to compare to anyone else.

One day = 24h. I wish I could code longer D:

I regret not getting involved in back-end dev earlier.

I come from a visual background so I was initially very attracted to front-end and UI / UX design, and begrudgingly did back-end work when mandatory.

Over the past year or so I've gotten way more into back-end, and am finding just as much satisfaction in this aspect of development.

Not ask help when i really needed.

Being working for others and not for what i believe.

• Not learning different and diverse skills earlier
• Not learning any front end development whatsoever
• Not applying TDD wherever I go

Not forcing myself into test-driven development sooner

Not seeking out code reviews from more talented individuals sooner

Not learning different styles of programming earlier (OOP & FP rather than just OOP)

Writing late night code and doing all-nighters and then wondering where all the bugs were coming from

Sitting all day every day for all these years.

Second regret: not developing another skillset outside of computers in general.
