Heavy imposter syndrome.

Hello everyone!

I'm seeking your advice because I'm stuck.
I have around 7 years of experience and I'm currently working on some open source project in the perfect team with super intelligent persons.

But I'm feeling like the stupidest programmer in the room.

I don't have any significant contributions ( in my opinion ) and I always lack innovative ideas. Most often my technical decisions are not the best even if I really try.
I tried to compensate it by working on the weekends on some pet projects but this made the situation worse because I'm not recovering myself enough.

What books can you recommend to somehow improve my technical skill?

Maybe I just need to accept that I can't be next Jon Gjengset and it's ok?

Thanks a lot for reading my vent.
