What is the motivation of your personality to do something

Your personality has a motivation for literally everything he does. Without this motivation, your personality would not be able to inspire you to come into action in the first place. The motivation is very simple: either get something, or avoid something. And in both situations it is a kind of 'win' situation for your personality, because it aims at either contributing to the desired outcome 'nice' or at preventing the opposite from occurring as much as possible.

Therefore ask yourself this simple question regularly: what does my personality believe he gains through doing this (and not doing something is also a form of 'doing', one where you choose to not take specific action). And this question can be applied to literally everything you do, even the smallest of things like zapping the tv channels, taking a shower or calling your mother. These small situations are often more easy to start with because your personality usually has not invested very heavily in them, and so they can help you to get the hang of this. A simple practice which can be used at any moment, in any situation, in order to become aware of an important role of your personality in your life: the one of coming up with your motivations. A motivation is not right or wrong in itself, it is a personality mechanism that you may or may not choose to keep on repeating.

Seen from your inner Self there is no motivation that you can label as such, since whatever it is that you do is right the way it is, and your experience of your inner Self dos not depend on circumstances or actions. You are likely to still take a shower, and call your mother, however the intention with which you do this comes from another aspect within you, and 'so' will your experience of it.

Be not content with statements of your personality like 'I simply do this, I do not know why', since that serves as a convenient way to cover up his real motivations, thus trying to convince you that he has nothing to do with it. You 'know' the difference between these both aspects already, and especially when you start with practicing this, continue digging until you find the real motivation at hand, you will find one, only your personality is likely to want to hide it from your awareness.
