“What I think” versus “[W]hat I’ve learned”. Arguably, they are equally important. In my experience, I’ve derived more value from doing and learning (after planning of course), than thinking alone.
If you spend all your time thinking, and none of it doing, you’re either thinking inappropriately, or fear has overcome you. This is stopping yourself from doing worthwhile things. You don’t have much time. Evaluate what feels right and get on with it.
While you’re doing, it’s worthwhile keeping a note of how you overcame any obstacles and sorted out issues. Then, when you’ve done your thing, you can share with others: “Here’s what I’ve learned….”
How much greater to share what you’ve learned, than simply what you think?
