I am clueless. I have suppressed emotions and dont relate to most ppl. I dont smile because i am a perfectionist and hate my smile.

1. I'm sure you are very relatable.
2. Have some fun. Do fun things. Here's a general rule: do stuff you are likely to remember in 30 years time.
3. Smiling = happy, confident; I'm sure you want to be happy and confident. A simple relaxed smile resonates that. There is nothing like a "perfect smile"
4. The title does not correspond with the body of the text, but here is the wikipedia version for the meaning of flirt: "Flirting or coquetry is a social and sometimes sexual activity involving verbal or written communication as well as body language by one person to another, suggesting an interest in a deeper relationship with the other person"
