Obviously, no one has a time machine to go back, to give yourself financial or career advice years ago, knowing how it all ends up. But preparing for whatever change is taking place, the best time is now. Not tomorrow. Not next week or month or year. Now.
If you do not, then you'll look back five years from now and wish that you had done something different.
How is the world changing? What can you do to study now that will pay dividends down the road?
