It’s hard for me to listen to you preach when you don’t practice it. If you don’t practice what you preach then you don’t truly believe what you preach.
We shouldn't run from our past. We should face our past head on. Think of when a bear is behind you. You don't run or it will devour you. You face it head on and back away. Then as you get distance between you & the bear you can move towards what's before you with speed.
Finishing something doesn’t have to look like what it should look like. If your goal is to finish a book, what do you do if the book is terrible. If your goal is to learn then not finishing a book and moving to a better option is best. Screw what people think.
