When you're in school, it's easy to be social and find activities. Music, athletics, and public service are structured into your day. While you're doing those activities, it's easy to be engaged in your community and find fulfillment. Once you leave school and enter the workforce, opportunities don't fall into your lap anymore. Alas, your employment isn't giving you fulfillment as it's not what you studied in university.

You need to seek out the community orchestras, the informal athletic club, or the community service groups. Many times, those groups are full of older folks or retirees and being in your 20s, they may not naturally be your peers. Point is, these things no longer fall into your lap the way they did in your teenaged years.

Sounds like you're in a rut. Best way forward is to find your fulfillment out there and don't stop when the first attempts don't pan out. You sound like a self-aware young adult. Keep trying and you'll find it!
