You are not your work

It is rather easy to get overly attached to your own work, and take critics on your work as personal attacks. However, these critques may be people trying to improve the project as a whole. If you get overly attached to your own work, it may cause you to become overly defensive. For example, the project may need to pivot due to some new inputs and the work that you have done has to be discarded. If you do not detach yourself from your work, you may see this as an attack onto yourself rather than an move to ensure that the project succeeds.
