Surrounding yourself with the right people, being able to write down your goals, break them down into short term or long term. Plan daily what it takes to obtain the short term to make the long term. Have your branches on the tree, things you enjoy doing or things you want to explore.
That gives you the opportunity to branch out and try new things to see what you could be passionate about. You never know, you might set yourself up for the future you did not know existed. So, what will you do to prepare?
