Social media is a great way to expand your network and reach new opportunities. You need to follow, connect, and collaborate with people who share your interests, goals, or values. You need to find and join communities, groups, or events that are relevant to your field, niche, or topic. You also need to be proactive, curious, and open-minded. You need to reach out, introduce yourself, and offer value. You need to ask for advice, feedback, or referrals. You need to build trust, rapport, and reputation.
