…they’ll want to see you win:

If you ever feel nervous telling a friend or partner your good news, don’t. Get new friends or a new partner.
You can’t afford to have people in close proximity that don’t want to see you succeed, grow, and progress.
They’ll subtly hold you back with snide comments, negative feedback, and casual pessimism.
In the short term, they’ll have a small effect, but in the long term, they’ll lead you away from your potential and towards the same negativity that has consumed their lives.
