Today is my brother‘s 21st birthday. Congratulations bro!
You have become an adult by all standards now. Even by those way outrageous American ones. You’ve achived much, but don’t stop yet. There are so many wonderful things in life beyond of where you’re now.
I wish that you have enough energy to climb the highest hill around to see beyond the horizons. And then I wish that you have enough will to travel there (that is beyond the horizons, if you haven’t been listening).
There is a huge world out there with plenty of interesting and amazing stuff going on. There are plenty of interesting people. There is much to learn. There is much to find. There is much to gain.
Now that you’ve become totally adult, I hope you’ll explore the possibilities and push the opportunities even further. Good luck to you and welcome to adults!
P.S.: Being partially childish is a good thing too, by the way.
P.P.S.: Happy Birthday!
