- The amount of calories you need after 50 drops almost in half. You slowly become allergic to many foods. Regulate your diet better.
- Use it or lose it. That means the ability to climb stairs, walk, run, pushups, jumping jacks, but also play an instrument, type, write, do math. Go out of your way to keep doing these things. Get a personal trainer if you can afford it.
- Travel as much as you can now. It's more fun when you're young. Money spent now is worth more than money spent later in more ways than one.
- For your career, find your masterpiece, something only you can do that will either live beyond you or perhaps help many others. You may need to take some risks to find it, if you don't do that in your 40s it might be too late in your 50s.
- You can't time the market, but start saving now for your kids college or retirement. Just take the money out of your paycheck if you can and pretend like you never got it ... your living standard tends to expand to your income.
- If you don't have one, find a partner. It gets harder to find one after 40, and after 50 you may stop caring. It takes two.
