UURRRRGGGGHHHHH...... dammit.......

Well, it's not too late to make a career change. I know the older we get, sometimes it gets harder to do that. But, I think it's important to do something you really enjoy, so that way it doesn't really feel like you're going to work. Ya know what I mean? Do you have any hobbies? That's always a start. Just think about some of the things you enjoy and expand on that. I wish you the best of luck, I know things will work out for you.

Physics can be boring sometimes (I actually hated it in highschool and undergrad), but it's impossible to understand how planets work without understanding physics. I guess I can use Earth as an example, like let's say you live in an underground house below the surface of the Earth, there actually would be more gravity on the Earth's surface than below it and that's because some of the Earth's mass is above your head when you are in the house and that mass pulls up on you and pretty much cancels the effect of some of the mass below your feet which pulls down on you. Or let's say you lived at the very center of the Earth. I mean, not that it's possible to live there
but if you did, in that case, there would be no gravity at all. It would be just like floating in zero g in a spaceship or something. And that's because there would be equal amounts of Earth above and below you. Things on the surface of the Earth where we actually live (thank God) experience the most gravity. So, long story short, the longer our distance is from Earth into space, the weaker the gravity, the closer to the center of the Earth we get it also gets weaker. I could get into the size of the planets/atmospheres/escape velocity/black holes finite/infinite/speed of light etc. because there's so much more to it than just the planets themselves.
Here's a very interesting youtube to give a more interesting definition. We live life daily on Earth and we take a lot of things for granted. The forces of gravity (not just our own gravity) around us keeps us alive.

I could have just told you to google it, but I love chatting about it so..
Didn't mean to bore anyone.
