It sounds simplistic and a little bit trite but I am firm believer obstacles are of your own making. When something blocks your way it does not necessarily need to prevent or hinders progress.

That is, no obstacle is insurmountable, there is always a way to proceed. You need to believe an obstacle is blocking you for it to prevent progress.

Believe

I attended a seminar many years ago that focused on the power of belief.  The main tenant of the course was the belief of your capabilities was key to achievement.

Of course, believing is not an absolute certainty of achievement and reality can intrude, however, I strongly believe, and have observed over many years, overcoming an obstacle always begins with believing it can be overcome.

Knowing you can be successful overcoming any obstacle results in the elimination of obstacles.  If they exist it is because you allowed them to exist.

Changing Perspective

Sometimes the best way to overcome a perceived blockage is to view it from a different perspective.  Often what you perceive as immovable might only appear that way.

Accepting the need to modify an approach or accept an unwelcome fact is all part of breaking down barriers.  The question becomes “ Is there a way to achieve my goal in a way that is perfectly acceptable to me, even though it does not conform with my original plan”?

My personal observation is the answer to this question is always empathically yes.
