Learn skills you can always rely on.

1. Self-Discipline: Get better at ignoring the negative voice in your head. Get out of your bed. Go to the gym. Don’t listen to “I don’t want to.”
2. Personal Effectiveness: Learn how to maximize the results you can get during the 16–18 hours you’re awake. Get more done — effectively.
3. Communication: We think we’re all master communicators. But the truth is that we suck. Communication is both art and science. And our ability to work with others depends on it.
4. Negotiation: You negotiate all the time. With your spouse, kids, parents, teachers, friends, co-workers, managers, etc. Learn to get the best deal for all parties.
5. Persuasion: Learn how to get what you want in an ethical way.
6. Physical Strength & Stamina: Getting stronger is a skill. Pull your own weight. It’s something every human should be able to do.
7. Flexibility: Sitting all day long behind your computer or in your car turns you into a stiff being. Learn how to stretch your hips, lower back, hamstrings, and calves — the most common weak points of desk workers.

That’s enough to keep you busy for a lifetime if you want to do it well. Pick a skill that excites you. Get better at it. Then, pick another. And keep on repeating that process.
