What are you fearful of right now?
How has this fear held you back recently?
Can you reconstruct that fear to be empowering instead?
Create an affirmation or mantra that directly contradicts your fear to propel you forward.
Know that your fear can be as "big" or as "small" as you observe it to be right now. What I mean is, maybe this is a HUGE daunting aspect of your life currently. Or maybe, it's simply a posture on your yoga mat that you're nervous about trying for the first time.
Whatever it may be, do your best to get to the core of it. Understand where it's actually coming from. Notice if this core belief has been the source of debilitating behavior in your past and present.
Can you take back the power of this feeling (because remember, that's all fear is- an emotion), and let it be something empowering instead?
Let your fear TEACH you, rather than OWN you.
Let it teach you how to step the hell into your personal power.
And notice that when you do, you'll build confidence.
It helps me to practice with a mantra or an affirmation during this process, which is why I'm encouraging you to try that on.
