Step 3: Draw Upon Your Experiences
What have you done or would like to do?
What don't you like to do?
What have you been pushed into?
What are your hopes and fears?
No, this is not some psychological test. Although, this is the best place for DIY analysis and get non-expert advice.
Formulate your attitude.
What kind of personality do you have?
Are you a skater, goth, k'nex'er, or weenie?
What stereotypes are you stereotypical of?
Is your noggin crammed full of useless trivia?
Do you watch too much TV, or play way too much video games?
