Life just gets better and better. People say "if you could be 20 again with your knowledge and the salary you are on now, would you?". My answer is pretty much at 20 I knew everything, at 30 I realised I was too old to know everything and after 40 I just keep on learning, new experiences, new friends and new knowledge. Hell, I only took up shooting this year!
Like a lot of people have said here, life is what you make of it.
