Building a community to help young adults make friends is a valuable and needed initiative, especially since loneliness is common after school years. Start by defining your target group clearly and choosing a simple, low-barrier entry point, like a recurring casual meetup. Focus on creating a safe, inclusive environment where people feel comfortable showing up alone.

Practical details: Begin with a free or low-cost platform like a WhatsApp group or Discord server to organize events. Plan your first activity around a shared interest (e.g., board games, hiking, or cooking) to give people a natural reason to interact. Keep groups small initially (10-20 people) to foster deeper connections. Be transparent about your role as a facilitator, not a therapist, and set clear ground rules for respect and privacy.

Honest tradeoffs: Scaling too fast can dilute the sense of belonging, while staying too small may limit diversity. You'll need to invest time in moderation and event planning, which can be draining. Some members may expect professional mental health support; have a list of local resources ready. Also, attendance may be inconsistent, so patience is key.

Concrete next steps: 1) Test your concept with 3-5 friends or acquaintances to refine the format. 2) Choose a neutral, accessible venue (like a library or park) for the first few meetups. 3) Promote locally through community boards, social media groups (e.g., Facebook groups for expats or students in Utrecht), and word of mouth. 4) Collect anonymous feedback after each event to improve. 5) Partner with local organizations (e.g., libraries, cultural centers) for space or co-promotion, but avoid formal funding until you have a proven model.

Remember, your professional background as a social worker is an asset, but keep the community peer-led to avoid a power imbalance. If you're learning Dutch yourself, consider offering bilingual events to include both Dutch and international members, but this is optional. The key is consistency and genuine care.
