Everyone has strengths and they are good at something. You might be one of the millions of people who are working a job that does you no justice. You might have qualifications far and beyond what you are doing everyday. However, on a daily basis you can practice the things you enjoy and the things you are good at. When you focus on things you are good at it makes you feel good.
If you are motivated, you have the drive you need to make it through anything.  Driven, the book that equips you to become what you desire.
To rewrite and break free from your past, you must reinvent yourself and never forget your past but learn from what you hated about it the most. To do this, you need to change your thinking, your speech, and your actions, reactions and most importantly you're routine. You cannot change the current life your mind created, with the same mind that created it. You must change the way you think. Change your mind, change your destiny.  Break the creature of habit cycle.  This is a lot easier said than done.
We all have a lot of mental hard wiring by the time we're grown. It's a continual process to rid ourselves of this, as well as new programming that is thrust upon us as adults. Just remember, though you may be doing everything correctly in your life, you didn't write the rules, someone else did. Now, it's time to write your own set of rules.
