Exercise. Exactly how is not important. What matters is just being consistent. Eventually it becomes a habit that will grow with you.

If it’s difficult or frustrating, you’re probably trying too hard. Ease up next time. If it feels like a chore, you’re not doing the right activity for you. It should be enjoyable.

Not giving a shit about a lot of stuff. Opinions and so on. Drop what pulls you down.

(Yes there might be exceptions)
