There are no "rules" for setting a deliberate and effective intention. There are, however, some things I have learned in setting intentions for myself and with my clients that may be helpful.
Be Clear: Clarity is key to providing the power to create. Spend adequate time setting your intention so that it is true and honorable. There are times our emotions can get in the way of creating an intention. Taking some time to process through those emotions is important. I worked with a client, for example, in setting an intention for an important meeting with an employee where difficult feedback would be shared. The client's intention for the meeting was "I grow strong leaders who are set up for success." The client believed in this intention and he was angry at (even disgusted with) the employee. Part of him wanted to punish the employee not help him. It was necessary for us to work through that legitimate emotion before the client could commit to a true and honorable intention. Your results will match your true intention. My client felt very good about the way he handled this meeting and the outcome based on the work he did ahead of time regarding his intention.
Focus on the Present: Intentions are now. An intention is not about what you're going to try to do, want to do or will do. It is about now. Read these three sentences out loud to yourself.
o I want a career that celebrates my authentic gifts and talents.
o My career celebrates my authentic gifts and talents.
o I will have a career that celebrates my authentic gifts and talents.
Which sentence is more powerful? Which will help you make the best decisions to support it? An intention is not a request or an attempt. It is a commitment!
Say it out loud: Being committed to an intention is crucial in order for it to materialize (manifest). For many accountability increases when a commitment is spoken out loud. It is part of the magic of developing an intention statement in a coaching session. You have an opportunity to say it out loud to another person, hence increasing your accountability to the intention. If you don't work with a coach, share it with a friend or family member.
Short-term or long-term: You can set an intention statement for any timeframe. As you saw in the example above, I worked with a client to set an intention for a meeting. You might set an intention for the day, the month, the year, your life. If you wake up in the morning knowing you have a hard work day in front of you for whatever reason, you can set an intention for how you will approach that day. It might be something like "I am thankful for my job. I am calm, thoughtful and open." In Marci Shimoff's book, Happy for No Reason, she suggests readers set an intention for their approach to happiness. Part of the tool's power comes from its flexibility.
