It suggests that luck alone is not enough; one must also be prepared and proactive.
• "The harder I work, the luckier I get." Coined by American golfer Gary Player, this saying emphasizes the importance of hard work in creating opportunities for luck to manifest. It suggests that by putting in the effort and perseverance, one increases the chances of encountering fortunate circumstances.
• "Opportunity dances with those already on the dance floor." This saying, often attributed to American motivational speaker H. Jackson Brown Jr., implies that by actively engaging in life and being present in the right places, one is more likely to come across opportunities.
