We grow in jerky motions. Within seconds we feel a great understanding, these are the moments of awareness, these are the glimpse of enlightenment. The rest of the time we live integrating those ‘jumps’ of development, learning new way of applying these understandings into our reality.
And sometimes it feels as if we regress. And it's understandable that these times of 'downs' can be easily misinterpreted as regression to the 'old me'. But...
Remember you are not THE SAME anymore, you only can go forward.
You must consciously integrate new lessons into daily life, don't just wait until it all be figured out by itself since 'now you know'. Sometime just being aware of certain problem is enough and the problem getting fixed by itself. But sometimes not, most likely bcuz we don’t have full awareness and broad perspective on ourselves and here - you gotta use you will power, decisiveness and determination according to the problem.
And it's good to remember: going with a flaw doesn't always mean passiveness.
