In financial terms net worth is defined as “The total value of all assets in excess of one’s liabilities”.http://www.investopedia.com/terms/n/networth.asp The more you own, the greater your value. This concept does not merely apply to financial assets but is also applicable to your value as an individual.
Assets
An asset is nothing more than a “useful or desirable thing or quality.” http://dictionary.reference.com/browse/asset
The accumulation of these things (assets), tangible or intangible, are determinants of your value to the external world, whether it be friends, family, significant others, or employs. Your net worth is the total value of all of those assets.
Everyone has value. Every individual has a bank of assets they have ascertained (skills, education, character, etc..) . However, some have ascertained more in the way of such assets than others, thus appearing more desirable or marketable than their counterparts. Your goal is always to increase your net worth (your value).
Remember, the world is choked full of people who are vying for the same material achievements. You must constantly seek to build and improve on your asset portfolio (learn new skills, increase education, perfect your gifts). When you fail to move or improve you lose.
Always know your net worth

Often how one view his or her net-worth is a direct reflection of self-worth. How you see yourself will determine how the world sees you. Consistently commit to develop self-worth. “When your self-worth goes up, your net worth goes up with it.” – Mark Victor Hansen
Never give the power of valuation to others. Never let anyone tell you what you are worth. Letting people determine your valuation is a recipe for failure. Many will devalue you every time.

There are many attributes, capabilities, and tools that determine an individuals human potential, desirability, and/or marketability. Each individual should know their capabilities, skill sets, level of intellect, subject matter knowledge, gifts, talents, level of competence, etc… Every person should be able to concretely define those things that create value in them.
If you don’t know begin by creating an asset inventory.
Stay True
Be accurate in your assessment. Never over inflate your worth. One cannot build upon illogical ideologies and misconceptions. You have to see yourself clearly. Honesty is imperative. Before you can build for growth and improvement you must be aware of where you stand. Overreaching and dishonesty is a liability never an asset.
