This is such a wonderful yet very scary notion to explore.
There does come a point on our lives when we realize that our "circle of influence" does not really align with our goals and dreams.
I faced this reality a short while ago - with friends and with family as well. It is a difficult thing to do, however we must realize that if the people we spend the most time with are not positive, inspirational, etc. and only bring us down - well then the time comes to make that difficult decision to spend less and less time with those people.
It is very true that you are a mirror of the people you spend the most time with so choose your friends well. Choose to align with people who will make you a better person and who will help you grow and help you get to where you want to be, which will most likely be where they are.
It is a difficult decision - but it is imperative if we are to continue the journey we are on.
Go to meetup.com and find some local groups that are in alignment with where you are going. It's a great way to meet new people
