I've mentored more than 100 students over the past decade. It's something incredibly important to my life and wellbeing.
I suggest going to your alma mater or graduate school and asking them if they have a mentorship program. They almost always do and it's an easy way to get started.
There's a lot of different opportunities for mentorship as you can see from the comments. Find a specific demographic that you're passionate about helping. Maybe it's someone less fortunate, maybe it's a carbon copy of you. After you have that set it will be significantly easier to identify opportunities and organizations through which you can mentor.
I've been working with youth including teenagers and individuals in their early to mid 20s for the past decade. What you're experiencing is incredibly common, especially for wealthier white Americans.
What I have found to be the difference between individuals who are able to get out of this state and those who continue to struggle is an incredibly strong sense of self identity. Having a personal anecdote that is unique, filled with novel experiences, and ultimately ends with a call to action for accomplishing social good is key.
My suggestions:
1. Travel and live with communities that have very little. Experience their traditions, families, frustrations, and joys.
2. Think deeply about your purpose and whether American individualism can really continue to provide you with the life you want to live. It very well may, but it is an important question to ask.
3. Go for walks by yourself and narrate your personal story under your breath. Imagine the good you want to accomplish and pretend you're being asked why you do what you do. The more experiences you have the more cohesive your story will be and the more confidently you will be able to take charge of your purpose/destiny/life. Also, journal.
4. Always find ways to give back. Give your last dollar to the person on the street. If you volunteer do it with kids, perhaps at a refugee center. Cook dinner for your parents and siblings when you're home, or wake up early to surprise them with breakfast.
5. Surround yourself with people who are deeply passionate about what they do and haven't become lost themselves. I live in SF for a few months every year and have found these individuals nearly impossible to find in the city. Search elsewhere.
Good luck. You're thinking about these things and are clearly on the right path. Much love!
Statements like this are exactly the reason why I have always been hesitant about having a relationship with Y Combinator. Reminders to be courteous are welcome, but a ban of political "stories" is completely inappropriate especially at a time when minority voices are already consistently silenced.
