- don’t drink alcohol (or drink less)
- don’t smoke/quit drugs
- do regular sports
- sleep good enough
- engage in social interactions
But I’ve been doing that all my life! It’s not that I have a bad life, it’s not amazing either… but there’s always the “how can I make it a bit better”. The regular recommendations don’t apply, so I find it harder to make my life better.
It's easy to talk about removing negatives but if there is some positive you don't have it's very difficult to think about or talk about because you don't even know it is there. Thus there is a common fantasy that Dianetics-style you can erase a negative and become awesome but actually if you erase a negative you might just be... nothing.
Also, drugs or alcohol can be positive influences if you are capable of moderation.
