Yes! This is a self-perception thing. In reality its all about value that you bring. So many good points are written here on this post. But I would say: 1. Do not compare yourself to peers. Everyone has self-doubts and no one is fantastic at everything. But some will talk a great talk and try to convince others of their prowess. You just need to be you. Only you can sing your song. 2. Add value wherever you can. This is what the business pays you for. This is why they hired you. Think about it, if you were not providing value you would not be there. 3. Own your world. Take responsibility for everything you do. Work hard to do the best you can. 4. Above all, be there for the team. Just like the A-team, its made up of very different people. You are a key part of that team. 5. Finally, for your own peace of mind, learn more and study new things. This will give you the feel-good factor and increase your overall knowledge which will improve your contribution to the work and diminish the self-doubt you are experiencing now. Keep your chin up. I'm positive you are doing great.
