“The world is round and the place which may seem like the end may also be only the beginning.” -- Ivy Baker Priest
This is the proverbial, is the glass half full or half empty.
See, you really do create your reality based on how you make up meaning about it.
If someone says something to you, do you automatically assume it is bad? Or do you automatically assume it is good?
Depending on which way you choose to see things, will determine your choices, and literally determine your future.
You have a habit of being a pessimist or optimist. And if you want to change, you literally have to break the habit and form a new one.
This will take work. And man is it worth it.
