Take a look in the mirror.
Do you like what you see?
If you don't...
There can only be one reason why.
You haven't kept the promises you've made to yourself.
That's it.
Confidence.
Self-belief.
Self-worth.
Mental toughness.
These are all skills you'll build by keeping your promises and living your life in pursuit of your potential.
If you constantly made promises to yourself only to never follow through...
Do you really think you'll be able to trust or feel confident in yourself?
Do you really think you'll ever feel truly happy and fulfilled?
You won't.
Keep your promises.
If you don't love and trust yourself...
Nobody else will either.
