Facing uncertainties in life

I only have a few days left here before I head back to Europe. I'm filled with very mixed feelings. The nature parts of Japan provide me with a great sense of peace. Tokyo downtown (Shinjuku, Shibuya, etc.) brings me rushes of excitement and literal headaches at the same time. I quite like my colleagues here. They are more outgoing and sociable than my colleagues back in Europe. However, people here are quite stressed out, whereas coworkers in Europe are a lot more laid back. Since I get easily influenced by other people's stress levels, it is much healthier for me to work in Europe than in Japan. At a social level though, here in Japan people rush to help me out if I am in need of something, and it is very easy to find people to hang out in the evenings and weekends as most of the guys at the office are single. In my European office, most people have partners and children so I am on my own after work hours.

It's not like I get to choose to stay here anyways, but I felt like I made some friendship that I would like to keep, but I have no idea if I'll ever meet these people again. I don't know when's the next time I'll get sent here and how many of the coworkers will still be working here by next year. There is so much instability (not all bad ones) that I'm struggling really hard to stay centered and grounded. All the yoga philosophies and calming techniques that I've been studying over the past 2 years have come in handy to help prevent anxiety attacks right now. The asanas really are secondary to breathing and focusing techniques at the moment. There is so much uncertainty in life, even when times are good. I have a few really good friends who keep reminding me over the phone, Facebook and email to stay grateful and surrender to the impermanence of life. Learn to let go of the control freak tendency and try not to panic when I don't have total control of how my life will turn out... I've done what I can to get me onto a good path. The rest will unravel on its own... try not to be too anxious about it. Definitely easier said than done though.

I have a lot of friends who have stable jobs, are married, have a house and kids. I envy how settled they are (don't need to figure out what's the next country they'll need to move to get the next job contract), but at the same time, I know that I'll be unsatisfied with the jobs and the life that they're living now. I guess I'm greedy and want both stability and constant excitement in life.. I don't think life works quite that way.

I need to learn to be braver about life and about the unknowns ahead of me.
