I think Steve Jobs was onto something here:
“Your work is going to fill a large
part of your life, and the only way to be truly satisfied is to do what
you believe is great work. And the only way to do great work is to love
what you do. If you haven’t found it yet, keep looking. Don’t settle.
As with all matters of the heart, you’ll know when you find it. And,
like any great relationship, it just gets better and better as the years
roll on. So keep looking until you find it. Don’t settle.”
Not easy advise to follow.
