This. I think at times there's a certain mind trick you have to play on yourself. You have to believe something is possible for your own reasons irrespective of popular opinion. The insight is that popular opinion is often wrong or exaggerated or less relevant to your personal situation than you realize.

You are an individual. Nation-wide statistics are somewhat relevant - there can be more or fewer jobs available, and more or fewer people looking, and that does matter - but in the end, you only need one job.
