Journal Prompt Series - quiet the gremlin…

Last night, I was challenging my goals.. I have some really great goals set out for me it's just that they are a little too safe. In the process of pushing the goal post my inner gremlin came alive reminding me I'm not smart enough and not educated enough!
Well gremlin screw that! I am enough!
Have you ever experienced a moment where you were pushing yourself to a new level and your inner gremlin came to sabotage?
How do you quiet the gremlin?
