Great job! That is amazing that you were able to motivate yourself and accomplish something! As for number two: If it helps, you could try using the alter ego strategy: Don't initially expect to 100% be your new identity, or to be so 100% of the time. Have it persona embody your ideal self, and (especially) in specific situations that you struggle with, begin to "get into character" so to speak. And then actively work on gaining or improving the skills and qualities that are necessary for you to transform into the new identity completely, as well as replacing or eliminating those which are blocking the process.
