You’re going to have plenty of obstacles standing in between you and your dreams so it doesn’t make much sense to hang around people who mock and laugh at the life you’re pursuing. There are many things that will happen to us that are unavoidable but choosing who we hang around with isn’t one of them.
Life is simply better when you’re around people who are positive and are supportive of your dreams. If you don’t have any people like that, you can start attracting them by becoming someone who lifts others up. You’ll likely get further in life when you have people who help push you in the right direction rather than having people who hold you back with their negativity.
