What makes us change?

Several things can drive us towards change:

We may have come to 'the end of our tether' - reached 'the final straw.'

We may be suffering so much that we don't feel we have the option of not changing.

We may be simply bored with how things are.

The energy we put into change is determined by how desirable our goal is and by how likely we think we are to succeed. However, we're less likely to change if we believe that doing so would cause us a great deal of upheaval.

Commitment = (desirability of goal X probability of success) - the upheaval of change
