One of my deep-seated beliefs is that happiness is a choice.
Obviously there are some natural temperaments and life circumstances that make being happy easier or harder, but I think you have to tell yourself your happiness is in your control.
Even outside the big pillars of life like health, relationships, and work, we can have a lot of control on our daily internal experience with things like:
- choosing to reframe losses as learning
- being happy for others' success instead of jealous
- looking for the good instead of bad in people
- focusing on what we're grateful for vs. what we lack
- looking forward to good things vs. dreading bad things
- etc.
