Step 1: Define "successful".

Hi, Eric.

1. Think big.

2. Find what you love to do and do it.

3. Learn how to balance life.

4. Do not be afraid of failure.

5. Be a person of action.

6. Avoid conflicts.

7. Don't be afraid of introducing new ideas.

8. Believe in your capacity to succeed.

If you're asking for advice, the title should be "How do we become successful in life?" { There are other ways to write this question, too. }

The way you and Karen wrote it { * How to become <font style="background-color: yellow;">successful</font> in <font style="background-color: yellow;">your</font> life } indicates that you are going to give advice. Those are not question forms.
