If you allow yourself to feel like an outcast because of something you don’t have that others around you do…or if your sense of self worth is defined by how well you fit in with those around you…life is just going to be one “keeping up with the Joneses” scenario after another. Seriously, don’t fall into that trap.
Sounds like you have a great opportunity to improve yourself and open many doors in your future. I’ve been there, so let me spare you the suspense - as someone from a low income family, you are different than many/most around you, and that will not change throughout the course of your life. Even as you accumulate status and/or wealth, that will not change. Many/most of your friends and colleagues will not know what it was like to grow up the way you did, or how hard you had to work to get where you are. Take pride in the fact that you are different.
