I'd say that when I'm meditating, 90% of my out-of-the-blue thoughts fall into categories like:
- A: seeking out little acquisitions (life/work hacks, low hanging fruit, new tech skills I could tackle today to improve my life) - B: chores I need to do and social debts - C: money, and whether I have enough - D: what will the future be like? - E: food, sex, safety - F: "this is nice, I'm not thinking of much"
I don't feel like these are good or bad thoughts, since they all have their time and place. But I do expect/hope that as the session progresses, more and more time is spent in state F.
I think one benefit of these labels is that instead of trying to re-articulate what you're thinking every time, you just drop it into buckets A-F (or whatever your personal buckets are). Making that task lightweight keeps me from overanalyzing the thought, at the risk of maybe oversimplifying my thought landscape.
By wrong I don't mean to say you're doing anything wrong, but it's not in the spirit of objective mindful meditation.
From my own practice, it's help me to accept the good and bad times, or what I'd usually think of good and bad, as more of a movie and put the bad times in a little more perspective.
