Hi, if you are not happy with what you are, then becoming what you want to be is pointless. Because once you become that, you will be what you are and you are unhappy with that. So it is absolutely vital to confirm what you are, i.e. fully accept with love who you are (that's the most important and also most challenging change) and from that place make progress towards "more" or "different". However, if the starting point is "I am not enough", then no matter what your practical achievement is, there will always be the need for more. Hope it makes sense.
"You will never have a greater or lesser dominion than that over yourself." Leonardo da Vinci. Without self control and self mastery there is no freedom. That means knowing who / what you are, adjusting and improving - life-long journey.
