So much time is wasted trying to distract one's self from what you are doing. Stop thinking about it as procrastinating. Stop saying you wasted the time. Just stop a moment.
One of the key points of the Taoist mind is self awareness. Know who you are, what you do, and why you do it. Accept your distractions, now understand them. Didn't want to clean your place, so you played that new game. Awesome, you did something. You got closer to beating that game you bought, instead of letting it get dusty on a shelf.
Stop blaming yourself for what you do, realize what you do. Once you begin to eliminate the guilt, it will become easier to do what you need to be doing. Let yourself do those activities you want to, stop making them an excuse. Choose to do what you want to do.
Blame and guilt are your enemy. Stop wallowing in guilt and blaming yourself for what you choose to do. Accept who you are, accept what you enjoy and admit it without shame. Once you have gotten past that, once you are free of your self pity, now you are free to complete your next task. You are free to choose.
