Tenerife Bluetrail 73k by UTMB 277/456
Since Dec -19kg, since Oct despite tons of work, conference appearances, consultations, I haven't missed a single training session. I don't have predispositions, but I also don't have excuses.

The real issue isn't that developers occasionally violate the Common Reuse Principle - it's that many aren't even aware it exists. You can't follow a rule you've never heard of. Stop chasing framework features when you don't know the basics! 🎯 #SoftwareArchitecture #CleanCode

📁 When you split every TS interface, type, enum etc into its own file, you're not practicing "clean code" - you're creating navigation hell. Having to jump between 20 files to understand one feature is cognitive overhead. BUT it's only one of the plethora of cons in this bad approach #typescript

🤔 Unpopular opinion: Being a 'passionate programmer' 24/7 is overrated.
Having interests outside tech makes you:
More creative
Better at problem-solving
More relatable to users
Mentally healthier

🔍 Code review tip of the day:
Review the tests first, then the implementation.
Good tests tell you what the code should do.
Bad tests tell you what you need to ask.

🚀 Best productivity hack I've learned:
Default to saying 'NO.'
2 y. ago, I made New Year's resolution to automatically decline new commitments (with room to change my mind later). Result? Most productive year of my life.
Saying NO to good things lets you say YES to great ones
