In this profession, there’s no end to learning. Asking questions doesn’t always mean you’re dull, be curious. You can learn from anywhere and anybody, even interns!
The industry is changing everyday so if you have any opportunity to refresh your knowledge jump at it. It will give you an edge over your colleagues who are complacent.
As with everything in life, humility will take you far. Always ask people to critique your work and when you do get them be grateful, you won’t grow without them.
We all have our preferences but never aim to be a niche writer or presenter when you’re starting. Do any and everything, know a little of everything.
