Hi rukspc, I'd say that everyone is going to have strengths and weaknesses. And lacking "common sense" in some areas certainly doesn't make you "less than". I'm sure you have got other good qualities about you that maybe some people with common sense/street smarts don't have as much of. Qualities that matter.
So do you think it might help you to focus on/value them in yourself a bit more??
Still, the "street smarts"..........if having less of those is leading you to be hurt in some situations/a real problem...........then it might seem like they're something that come naturally to people. but not always necessarily.
And there will be things that can be picked up on. So maybe checking out, reflecting on other people's experiences and learning from them might help a bit??
But if that's an area you still struggle with..........well plenty of room in this world for all sorts of personalities and there will be a lot more to you than having less "street smarts".
So just try to be yourself as much as you can, hey? Try not to deprive you or others of that.
