"When someone gets between you and your goals, the best thing to do is pull his shirt over his head and punch him in the face a few times. "
Of course this was in my old job where I used to be able to do that with the only penalty being a five minute time out.
In business however you cannot use these tactics. What you can do is be relentless in your pursuit of your goals and move forward in spite of obstacles, naysayers, or bumps on the road towards success. Those of us that have faced these challenges are cognizant that there are people and things that get in the way. But, you can obtain anything you wish if you are willing to live with the bumps and bruises along the way. Some people call it paying the price. I call it resilience.
