If you are not succeeding, I know your problem.
You don’t believe you have what it takes to succeed. You don’t believe you were born to succeed. You don’t believe, what you are doing is good enough to make you succeed.
You have a deeply engrained lack of self confidence in you.
Unless you reverse the present thinking you have about yourself, you will remain where you are.
Reverse your thinking:
From lack of belief to belief;
From negative to positive;
From doubt to certainty;
Failure to success.
I encourage you to do this. If you do it, your success will be guaranteed. Nothing will stop you.
