Great post Sebastian. I want to add one point: spend time with people who are older and younger than yourself. This would probably constitute family for most people. I can’t explain why yet (perhaps it gives us a sense of where we are coming from and going), but occasional interactions with old people and young children always leave me feeling richer. I found these interactions especially lacking when I was working away from home in the U.S.
A brief comment, but I think there's lots of wisdom in that. I'm sitting and reflecting on it for a moment.
I think Raunak is on to something here. You can absorb a lot of wisdom, poise, and maturity from people that have been there before you, and pick up a lot of energy, fun, and spontaneity from kids.
I was in a cafe a few weeks ago and a young kid was going around with his finger like a gun going, "bang! bang!" at people. Most of the adults were ignoring him, but I ducked under the table and put up my finger to shoot back - 'bang! bang!"
Anyway, we got into a little shoot-out, and everyone was laughing and having a nice time. Reflecting on that, interactions with people of different ages... yeah, it's good stuff. Cheers for the comment Raunak, that's worth thinking about.
