Achievement. A Paradox
The sense of achievement can feel great, but many people are too busy to notice that the feeling of achievement is transient. Or... They may convince themselves that the same sense of achievement will always feel great.
If that's what you do, you are living from the energy of past accomplishments and you are not achieving much in the present moment of now, but if you live your life in the moment of now, you are in a constant state of achievement, you experience an 'aliveness'. You become dynamic.
However, there's a catch. A paradox. (A paradox is something that seems to contradict itself, but does not. A paradox is more like two equally true statements that seem to oppose each other. For example, if you keep going to the east you will end up in the west).
The paradox here is... If you never 'celebrate' your successes, you may one day in the future, wake up one morning and find your achievements don't mean very much and if you keep celebrating your successes, eventually they will still not mean very much, neither will the celebration. In this scenario the paradox is getting you very close to 'cosmic truth', probably too close for comfort.
For example, what does it really mean to you that Man has walked on the moon? Do you really feel you want to rush out and dance in the streets? No? Why ever not? As I said earlier, the effects of achievement are transient. Been there, done that, so what. But to feel a sense of achievement is necessary for us to get a sense that we are living fulfilling lives.
It's the nature of growth and development of all life. It's the law of evolution.
You can find a myriad reasons for this if you want to, but there's only one true answer... Because it is so.
So if you want to feel fulfilled in your life, you have to stay committed to the process of growth and development and live in harmony with life itself. Keep promises, agreements and appointments you make with yourself and others and never change your mind once committed. Flexibility, can be a beneficial trait, but should be employed BEFORE you commit yourself, but then keep your promises as if your very life depends on it. This way you are ensured of a more powerful path to the achievement of whatever you aspire to in life.
If you really want to transform the quality of your life, take these ideas on achievement and use them like a sledge hammer to demolish all those aliveness destroying habits that you are aware you have. If you are not interested in personal transformation and growth, amuse yourself with something else, because the work of personal transformation is not for you.
