A thought about hurrying chess moves

I usually play chess on android phone or ipad on train or at work, in places where i am not concentrating 100% on the chess strategy. My long term goal is therefore to focus on creating isolated time slots where I am not disturbed, to improve on my abilities to look ahead for attacks or pins against my own pieces when I make a move. I also must improve on my sense of good and bad positions, by looking at how many chess pieces a piece is attacking and vice versa.
