tools available to us to help us meet demands. Considering some of the ways of categorizing resources helps illustrate the scope of these tools. One approach is to distinguish between tangible and intangible resources. Money is a tangible (and often quite useful) resource, as is physical help from a neighbor. In contrast, attitudes about yourself are intangible, even though they may strongly influence how you react to stressors. Another approach describes resources as personal versus environmental. Personal resources include individual attributes, such as intelligence, extroversion, knowledge in dealing with problems, and even attitudes about self such as self-esteem and confidence. Environmental resources include money, other people, access to information or tools, and so forth.
