"a lot of people miss the part where positivity is really a practice" - Absolutely, it needs to become a habit - which can be a challenge if, like me, you've grown up in a v-negative environment and have been conditioned by it.

Interesting your point about accepting 'what is'; most people resist what is, but accepting it (which comes from recognising that it's just your thinking that's the issue), opens the door to serendipity and 'good luck' - that's been my experience, at any rate.
