The user is gifted with an automatic infinite supply of luckiness, most have no control over this power as things considered "lucky" just randomly happen to them. Ergo, nothing bad will happen or if it does then their power will always sort it out and keep the "lucky" side of the scale the heaviest.
People will always respond positively towards the user and they'll never be drawn into a fight. People would voluntarily give user money and such and just genuinely be nice to you and respect you.
All aspects of users life improve drastically: love life, work life, personal life, financial life and basically life as a whole would become easier, happier, and would excel altogether.
