At the start of your career, you want to listen, watch and write everything down, and take pictures or make drawings!
Taste everything, learn flavours and textures and understand how they complement other foods and how they work together. Don’t rush your development or push for promotions too early; these come with time and experience. Focus on knowledge and skills and your development will happen naturally.
And most importantly, keep your knives clean and sharp! Spend some extra time every night sharpening and looking after them, they are your second most important tool after your brain.
