What success looks like for one person is very different for another. In the absence of creating our own definitions of success, we often take on society's definition. This usually involves credentials, status, power, or lots of financial wealth and material items. At the very least, we are conditioned to think that if someone has a lot of fancy things then they are "successful." But society is often misdirected, and things such as wealth, status and material possessions, while look cool, do nothing for our universal need for purpose, fulfillment and meaning. It's often a harsh reality that people have to discover for themselves.

Here are 20 truths about success - defined as the accomplishment of an aim or purpose that are rooted in science and psychology. Most people aren't aware of these truths, but they're essential to know:

1. Your IQ doesn't matter as much as you think.

2. What looks good to others is less important than how it feels to you.

3. Extrinsic rewards such as money, status and fame do not make you happy.

4. If your intellectually challenged and the impact of your work is aligned with your purpose, your performance will soar.
