My biggest lesson ever ever ever is that just because you’re worried that something won’t work out don’t make the decision for it to end and not work out just because you’re scared. Learn to face those fears by just writing it out and letting things run their course or telling the person if it’s a person that’s involved that you’re scared or tell yourself or if it’s a boss or whoever but don’t like make things and like break up or quit or whatever because you’re worried about what will happen. You can end things based on what is happening or has happened, but don’t do it based on what you think will happen or could happen.
