Sometimes, there are very tangible barriers between us and the things that we strive for. For example, these may include transportation, financial costs, or limiting insurance. On other occasions however, you may just be your very own barrier.
Have you ever found yourself responding, “Yes, but...” with increasing repetition? It is similar to an apology followed quickly with a “but”. Everything that came before is now forgotten. You still had a point to make despite apologizing.
So, although you've said yes to whatever suggestion or opportunity has been presented, you have really already discredited its value or possibilities.
Try catching yourself before the “but” has the opportunity to rear it's head and replacing it will a thought that may still allow for the opportunity.
