Oh it definitely applies. All my life growing up my dad never really acknowledged or praised what I accomplished, only ignored it and then criticized everything that was wrong with me (and the rest of the family), and my mom was always full of fears and low self-esteem (only worsened by my dad's cruel criticisms), so yes, all my life I've always internalized that my best is never good enough, no matter how hard I try. I'm such a hard perfectionist and I ALWAYS berate myself internally for not working hard enough or not doing a good enough job.
