"The things I want to do, think about and talk about are just not the things that others want to hear." That's not an unusual complaint.
The problem is, how can I talk about my interests without being boring to others? Ask yourself some questions:
1) Why am I interested?
2) How did I become interested?
3) How might this topic impact the person(s) I'm addressing?
4) What are the interests the person(s) I'm addressing?
First, why do you find certain things interesting and others not so interesting. There must be elements in your choice of ideas and activities that have led you to spend time and energy in that area. What are those elements?
Second, how did I become interested in these ideas and activities when many of the people I know haven't demonstrated any particular interest? These elements may very well suggest a path others will recognize and understand. People who may know or care very little for your particular interest may be able to understand why somebody would be interested.
Third, what impact can you think of that might impact those you are addressing that is directly related to interest in your topic? Much, if not all of us are impacted by changes that we don't know about or wouldn't even approve of if we knew about them. We are still impacted and anything that affects us is likely to hold our attention.
What are the interests of the people you are addressing? They are and probably should be centered on their lives. After all, if they don't take care of themselves, who will? Enlightened self interest has a positive ring to it. Certainly more positive than selfish. But, that is a very good place to begin. You should find a wealth of possible ties when you view the enlightened self interest as it relates to your own interests.
