Yes it is necessary to shift your identity, to change the way you think, feel, act accordingly to your desired reality, BUT..
Do not fall into the trap of putting to much importance into the person that you are becoming.
Otherwise you will become too Self-conscious and all you will feel lots of pressure upon you.
Instead you can use this mantra : "I show up as I want, regardless of others"
You can start gently playing with your identity and trying to show up as your new self, and not forcing it.
Patience is also key, so be your 2.0 the best you can, but don't feel bad if sometimes you remain your old self, it is absolutely normal. Rome wasn't built in a day.
Have a great week everybody !
