Passion is a force that drives your goal, it helps you put in your best no matter the odds you encounter. It acts as a relentless drive towards achievement. As important as your goal is, you need to be passionate about what you do.
It is not every time that your passion equals your goal. It is very possible to have a goal set with excitement but at the end of the day you loose that excitement because your passion to do is below the standard of your goal. It is not like you don't have passion in you but at that point you lack the passion for the set goal. In this case you have to develop and build your passion to seeing that your goal is achieved. First You have to ask yourself these questions; Why did I set this goal (purpose)? How important is this goal to me? Does it add value to me as a person and also to others? Once you are able to answer this questions it helps you build the right passion for the set goal.
You have to keep reminding yourself of the purpose for your set goal. When you have a passion for what you do or what you want do it makes it quiet easier to get things done not because there are no challenges but because you are passionate about it you look beyond the obstacles.
If you ever get to that point where the passion seems to be dying you have to rekindle it and keep reminding yourself of the why. If you don't have passion for something, you will be persuaded or pressured to do anything and the outcome of such is always very poor. Prioritize your goal, understand how important it is to you and put the right passion into it !
