Man is not worried by real problems so much as by his imagined anxieties about real problems
EpictetusFreedom and happiness come from understanding - and working with - our limits. Begin at once a program of self-mastery. Stick with your purpose. Do not seek external approval. Do not worry about anything outside of your control. The only things you command are your thoughts and actions. We choose our response. Stop aspiring to be anyone other than your own best self: for that does fall within your control.
EpictetusIs freedom anything else than the power of living as we choose? Nothing else. Tell me then, you men, do you wish to live in error? We do not. No one who lives in error is free. Do you wish to live in fear? Do you wish to live in sorrow? Do you wish to live in tension? By no means. No one who is in a state of fear or sorrow or tension is free, but whoever is delivered from sorrows or fears or anxieties, he is at the same time also delivered from servitude.
