Great tips!
I've shared a ton of ideas in Volume 1 of my Dev Concepts collection:
Learn to type FAST (80+ WPMs)
Master your Operating System: its shortcuts, how to manage processes, how to navigate the file systems, etc
Learn IDE shortcuts (create/rename files, extract methods, classes, functions, implement/override/refactor methods, etc)
Automate code formatting, and anything else that wastes time and brain cycles
Write tests
Use the Terminal and master aliases to automate repetitive tasks and type less
Use mind mapping, diagrammatic reasoning & problem structuring techniques to analyze problems & tasks
Create mental models to better understand what you're doing
Practice practice practice!
Contribute to open source to learn from great developers and improve
Learn to search efficiently
Use design thinking, 6 thinking hats and similar techniques to increase your creativity
Structure your work and tasks (create yourself a system to be super organized & efficient); Read about GTD
Estimate tasks using relative weights to better compare them
Prioritize work regularly (focus on urgent & important)
Plan your days ahead
Build solid habits
Become a morning person & focus on the most important task as
soon as you can (highlight for the day -- miracle morning & Make time techniques)
Manage your time. Learn about techniques like Pomodoro, use a time timer to visualize time
Work in a structured manner
Focus (for real!)
Focus on outcomes rather than on details
Take advantage of downtime to improve (learn new things, contribute to open source, etc)
Reflect on work regularly (identify your weaknesses)
Broaden your horizons and learn about architecture, software design, back-end, front-end, infrastructure, etc
Master all the general concerns (e.g., error handling, code quality, logging, performance, i18n, l10n, encoding, caching, how to fix bugs, source control management, security, etc)
Find your Ikigai and stay motivated
Have fun
And there's a ton more in there. Hope this helps someone out there!
