2. Appropriate Eye Contact Goes A Long Way
When people get nervous, they tend to avoid direct eye contact. However, avoiding eye contact also shows disinterest and aloofness.

Then look away and smile. After a few minutes try the same again. This flirtatious eye contact sends a clear message of interest.
