Stop thinking about your passions and start doing something. Take a risk, and step out to try something new. By challenging your fear with action, you'll not only raise your self-esteem, you'll expand your comfort zone. If you're not sure of what to do, ask a trusted friend or partner for ideas. Remember that good luck happens when you're in action. And, if you try something new (even if you're not sure of the outcome), you may discover a passionate interest by accident!
