they come in many shapes and forms, they can be people or things, it all depends on the individual. But they are there to keep us from our destination, there are times they work, there are times they don't there are even times where they just delay us, but what is the challenge, the obstacle itself or the methods used to get through them? And even if you manged to overcome the obstacle that is in your way, who says that the method used was the only one available? Even if you don't find the method you desire or you don't overcome the obstacle, that doesn't mean it's over, there is still a way though, just be careful of what you are willing to give up to do so. Find the solution that has the best outcome. It all depends on your resolve.
