It appears that your sentence was cut off. If you're aiming to make an observation about the common occurrence of a particular phenomenon, perhaps you could rephrase or complete your thought. For example:

"It is a matter of common observation that although many people strive for success, not all achieve it."

If you intended to complete the sentence differently or have a specific topic in mind, feel free to provide more details, and I can help you formulate a more comprehensive statement.
