Time management is hard! First, we often focus on "urgent" things at the expense of what really matters. Second, we usually don't control how we spend all our time.
You have to be prepared to ADAPT your goal plan, and you need to break your big, long-term goals into small, short-term goals.
Being realistic about your future will help you avoid procrastinating, because you'll understand more clearly the value of what you do now.
Be generous with yourself. Block out time to do the things that really matter.
