fake it till you make it is the worst strategy for you to deal with imposter syndrome as a developer because that's like playing poker with your mind you are telling it something but the mind tells you something else and the mind usually wins we effectively get rid of impossible synonym forever you need to address the core issue behind that is why are you perceiving yourself as worse than the developers around you and this happens mainly for two reasons number one you are interpreting your past experiences as failures stop that understand everything you've done whether it's an interview a code review
even bad feedback from your Tech lead everything it's simply a data point data points that represent your performance at a given point in time that's it they don't represent you as a developer or as a person the second thing is that you gotta stop comparing yourself to others all together instead focus on messing your craft and understanding it at a deeper level the biggest Geniuses out there Picasso Michelangelo they didn't focus on what the person next to them was doing they focused obsessively on their disciplines and that's how they got to levels never imagined before so separate yourself from your work get a
more accurate data on your performance and don't label it focus on master and you'll never feel like an imposter again
