I think these findings are especially relevant given that so many of us announce our plans to engage in identity-relevant activities on Facebook (e.g, "Starting my marathon training today" or "Going to be at the library all weekend"). We then get social recognition in the form of likes and comments. Perhaps now you will be conscious of how these habits might actually hinder you from enacting your plans and reaching your desired identity!
