Before proposing, get to know the girl well and establish a strong friendship.
Choose a romantic and memorable location for the proposal.
Prepare what you want to say in advance, but don't memorize a script.
Be confident and sincere when you propose, and express your feelings honestly.
Be respectful of the girl's response, whether she accepts or declines your proposal.
Don't pressure the girl into saying yes, and give her space to make her own decision.
Consider her preferences and interests when planning the proposal.
Be prepared for rejection and don't take it personally.
If she says no, remain friends and continue to treat her with respect and kindness.
If she says yes, celebrate and plan a future together.
