I think the thing that has helped me the most is a philosophy called Stoicism and a book called A Guide To The Good Life, and specially a tool in it called negative visualisation. Basically you just imagine the worst case scenario for every situation and accept it.

Also, meditation really helps.

I think anxiety will never completely go away, ever, because it is part of the human condition. My goal is to be fine living with my anxiety, knowing every aspect of it and gaining control over it, but with the knowledge that it will always be there.

Cutting through the bullshit:
- understand that you're not your thoughts
- eat healthy food, sleep well and exercise
- have safe harbours: money, relationships, communities, family
- meditate every now and then for a few minutes
- always plan everything so you don't get overwhelmed
- study philosophy, old books have the best advice
