There are two groups you can be in:
1. Those who do what they want to do.
2. Those who talk about those who do what they want to do.
Group 1 people do not concern themselves with the actions or opinions of Group 2 people. If they did, they would be in Group 2.
There’s no in-between. No gray area. If you’re not sure which you are, you’re in group 2. People who do what they want to do are pretty sure about it.
