Will be is not good, better(did also cut out alpha not sure if energy will know what to do):
In a positive and healthy way, I´m confident in my self and in my abilities, including leading others, I´m in control over my own life for now and forever. x18
Not super happy about the including leading others part, you may find a better wording.
Affirmation statements have to be stated to be in the present tense. Like what you are after already exists. Energy does not understand what something can be or can not be, it just is. You have to mold it.
Ofcourse even tough i know about affirming energy in the now, Its still hard to word it right :? That's why i ran it by you guys first :P
I put in the Alpha part because to me it means being strong, Confident, Good leader, Steadfast and to know how to handle all situations. As far as i know the thing that matters most when doing any kind of working is the intent, Make it short and to the point. So i think that alpha would do well fin this case, But i can be wrong ofcourse correct me if i am.
How does this sound:
In a positive and healthy way, I´m confident in myself and in my abilities, From now on and forever i am a alpha over my own life.
The leading others part can be tied into the alpha part so i left it out completely, Being in control over my own life can also be tied into: I'm confident in myself and my abilities, So i don't know if it would be necessary to it point out. What do you think?
