So true!
Goals give meaning to your life.
Without goals you'll get indolent and not happy at all.
Do a mix between achievable goals and high goals, so that you reward yourself by achieving goals, while you always have greater goals to reach.

I've also written something about setting goals on my last post
'how to Motivate yourself'.
I know that you're interested in these topics, so maybe you want to have a look. :)
