"There's a difference between interest and commitment. When you're interested in doing something, you do it only when it's convenient. When you're committed to something, you accept no excuses; only results."- Kenneth Blanchard.
Interest and commitment are not the same and although they seem to be like the same, they are cut from different cloth.
One is driven by an inbuilt desire to keep going while the other is acted upon based on how convenient it is.
Interest is "the feeling of wanting to know or learn about something or someone".
When you have interest in a thing, you most probably will do it when it is convenient and it doesn't have that pull to drag you towards completion.
Commitment is "the state or quality of being dedicated to a cause or activity".
With commitment, you push through even when it seems tiring and impossible to continue. Commitment is like a contract that needs not be broken but delivered on.
You must show commitment to a thing to make it worth the effort because, interest can only get you as far as when you find the time to.
If it doesn't make you want to stay dedicated, it isn't commitment but one of interest.
Success is bewitching and when you see yourself getting to that point where it must be done, you see yourself staying the cause not minding the fails and difficulties that trails the journey.
People who do thing because it interests them, do accept excuses, in fact, they give excuses and can do without results.
While those who do things based on their level of commitment, accept no excuses and are result driven.
