With there being almost 8 billion people on earth there are bound to be many people who have the same interests, passions, and hobbies as you. With having a community of like-minded people, you are able to connect with them by exchanging ideas/strategies/art/whatever else you all might have in common! Keeping in contact with those who have the same goals as you often times help you stay focused and grow within your craft.
But what if they have more experience than you? What if there are so many people that have the same ambitions as you and you feel you're getting drowned out by the crowd? You may think 'How am I able to pursue the same thing if there's already so many other successful people within the same field'? It can be disheartening when these negative thoughts of comparing yourself to others creep into your head.
It's important to remember that other's success won't detract from yours. Success is not sand poured out from a jar that will eventually run out. You have a specific set of skills that provides value which others can benefit from.
