Ayn Rand

Just one comment - it has been shown that happiness comes from altruism and. She would have to incorporate that into her philosophy if it truly is objectivist (i.e. based on reality) as she says.

7 steps to Happiness

1. Invest yourself in closeness: Of all the circumstances happy people share, loving relationships seem the most characteristic and most important. So when you're setting your priorities, time for your loved ones should be No. 1.
2. Work hard at what you like: If love is most important to happiness, keeping busy at work you like may be second in importance. If your job doesn't fit that description now (or look like it will in the near future), search hard for ways to find work that satisfies your very real need to do something that is meaningful to you.
3. Be helpful: Altruism builds happiness in at least two ways. Doing good makes you feel good about yourself. In psychological terms, it enhances self-esteem. And there's evidence that altruism relieves both physical and mental stress--thus protecting the good health so important to most people's happiness. (See "Beyond Selfishness" and "Helper's High," October 1988 PT, for more on this.)
4. Make the pursuit of happiness a priority: All things may indeed come to he (or she) who waits, but why wait to feel good? Discover what makes you happy and make time to do it.
5. Energize yourself: Run, play a sport, dance--the choice is yours, as long as you keep aerobically fit. Whether the feeling of well-being produced by exercise is due to the release of endorphins--the brain's natural painkillers--or something else, researchers agree that fitness is one reliable road to happiness.
6. Organize, but stay loose: It's good to know where you're going and to make plans for fun along the way. But since novelty makes us happy, be ready to seize an unexpected opportunity to try something different.
7. Steady as she goes: We all have our highs and lows, but strive for a sense of perspective. Emotional intensity can be costly. Those who hit the highest highs tend to reach the lowest lows as well.
