Though I am able to focus deeply I find it difficult to be as productive as I can in that time. I still take too long! Any tips?!

Practice makes perfect. In time certain things will become faster to make. And then others. But keep in mind that speed is not equal do productivity or good results 😉

Sit back and relax. Don't be so harsh on yourself. Things will start wokriking for you the way you seem them. Keep doing the practise on regular basis.
