Depends, your title is slightly tangential to the OP without further context.
You just have to focus in improving as an individual because that's the important point of view in your reality. Many people keep running & are proud of their progress despite the fact that they'll never reach Usain Bolt's level.
But, who cares. Find enjoyment in putting your own potential to the task at hand, the potential of others is irrelevant in your life, in this aspect at least. With enough motivation and passion for what you do, you'll probably keep getting better (while you do something you like), while the skill of others is ultimately inconsequential and is not an integral part of your life's paths.
