This is the world of "counting" what you are doing, being aware of it, and responding to it in a constructive way. It is causing attention to what is going on, by noting it in "black and white", rather than letting it drift out of the mind and/or letting the primitive mind produce "deniability" (of reality).
It increases the productivity and quality of life by 100%+.
Accountable: Obliged to account for one's acts, answerable. If one is responsible, one answers for what one does and what one promises or commits to. In that case, one chooses to have one's word be determinate of what will happen; one honors one's word, for the benefit it has on one's self opinion. (Re: honoring one's word: The Integrity Factor.)
Being accountable is simply having something or someone to "answer to", not in a faulting way, but just as a means of bringing it to light, similar to the purpose of one doing one's accounting work.
HOLDING YOURSELF ACCOUNTABLE
Accountability can exist in a simple internal promise to oneself, but it is more effective if it has more body to it, and that is the value of putting it in writing.
Putting aside time (usually in your Weekly Planning) on your schedule is extremely facilitating and it automatically sets up a time at which you are answerable to yourself for doing what you said you'd do.
ACCOUNTABILITY TO ANOTHER PERSON
Using a life coach, a consultant, business partners, business colleagues, or any "partnering" person is very helpful, as you have somebody to "answer to". And I guarantee that you'll be more likely to do what you said you'd do, as you'll feel a natural obligation and, perhaps, also a pride in showing that you can keep your word.
It is important to note that a person who does not want to step up and be held accountable might be sticking him/herself with carrying out a victim role. For sure, being willing to be accountable and to play the accountability game is a source of power. Being not willing to play it is a source of nonpower.
The penalties of not doing what you say lie in not getting the payoff of what you said you would do, but more importantly in the harm to you of the disappointment, tension, negative feelings about yourself, and the loss of or lowering of connection, cooperation, and love from others. High costs, indeed.
As you more strongly hold yourself to what you promise and intend, you will find yourself exercising immense power over your life, such that you will achieve your dreams. The pride and confidence you'll develop in yourself will be priceless.
And the trust that will develop in others will get you vast amounts of integrity, partnership, support, respect, and cooperation from others in creating that which you want.
That trust of others in you and of you in you, plus the pride and confidence you'll feel about yourself is beyond priceless.
