Caught between two worlds Hi my Name is Tobias and I am 31 years old. Of course there is a personal story behind my question and a lot of causes and conditions that led to my current situation but in brief the question goes somewhat like this:

What advice could you give someone who after a long period of looking deeply into buddhhism comes to the conclusion that there is actually nothing else to do in this life apart from practicing the dhamma (most preferably as a monk) but due to decisions earlier in his life this person is bound to live a worldly life (having two children to care for)?

The obvious answer would probably be to practise as a layperson and become a monk maybe in the next life :)

This sounds good in theory but I have come to realize that this is actually not easy to be done when you have no real interest in social interaction, seeing that most of the things people spend their time with are utterly useless.

So it is like being caught between two things where you can´t really focus on either one completely!

Thanks very much for your advice and opinion.
There is a lot you can do to make the best of your situation. I can tell you what's been helpful for me. 

Social interaction regarding worldly things can seem like a ridiculous waste of time; but social interaction regarding the Buddha's teachings can be energizing. Reducing your old ways of social interaction and time spent on entertainment can give you time to find others, both online and locally, who share your interest in the Buddha's teachings. 

A job can seem very dreary when the old ambitions you had no longer motivate you. But you can keep in mind that your job gives you the opportunity to give dana and support the Dhamma and that is really an honor, I think. Learning to live frugally so that you can give dana can be rewarding.

You can set a quiet, good example for everyone in your world by keeping the five precepts, following the noble 8 fold path, and letting it drop in casual conversation that you are Buddhist or that you meditate. You don't ever have to try to convince anyone about your beliefs. Just let your actions and demeanor speak for itself. Seeing positive changes in you may create interest in Buddhism or meditation in those around you. 

You can join in a sort of spiritual solidarity with monastics by keeping the 8 precepts as often as possible. That's good for focusing on your practice too.

When monastics depend on laypeople for support and laypeople depend on monastics for spiritual support and teachings, a wonderful synergy is created. And both sides of the coin are important. I recommend a book called The Buddha's Teachings on Prosperity at Home, at Work, and in the World. http://www.amazon.com/The-Buddhas-Teachings-Prosperity-World/dp/0861715470# It has many teachings directed at laypeople that you don't often hear and can help you understand the important of laypeople in Buddhism. 

Best wishes in your journey.
