You can't accomplish anything worthwhile if you inhibit yourself. If life teaches you nothing else, know this for sure: When you get the chance, go for it.
What I know for sure is that your life is a multipart series of all your experiences- and each experience is created by your thoughts, intentions, and actions to teach you what you need to know. Your life is a journey of learning to love yourself first and then extending that love to others in every encounter.
My highest achievement: never shutting my heart down. Even in my darkest moments - through sexual abuse, a pregnancy at 14, lies and betrayals - I remained faithful, hopeful, and open to seeing the best in people, regardless of whether they were showing me their worst. I stayed open to believing that no matter how hard the climb, there is always a way to let in a sliver of light to illuminate the path forward.
I think mentors are important and I don't think anybody makes it in the world without some form of mentorship. Nobody makes it alone. Nobody has made it alone. And we are all mentors to people even when we don't know it.
Keep a grateful journal. Every night, list five things that happened this day that you are grateful for. What it will begin to do is change your perspective of your day and your life. If you can learn to focus on what you have, you will always see that the universe is abundant; you will have more. If you concentrate on what you don't have, you will never have enough.
