Honestly why does it even matter? Why should one focus on if whether others believe in them or not?
It’s great having a group of cheerleaders who believe in us and everything we do but sometimes conditional and it’s not an energy source that you can draw from all the time.
When taking on huge projects and tasks, every day is a grind and you need to be energized and motivated for all that. Looking to the outside world for that motivation and energy is not wise.
It shouldn’t matter whether the world believes in you or not, self belief the most important drive. Believe in yourself, use that as fuel and keep going.
