PickTheBrain.com recommends considering what you may miss out on if you choose to opt out of new opportunities. There's always going to be the risk of failure, but there's also a chance for success - some of which you can capitalize on if you overcome your fear.
Once you change your mind frame, you can also begin to see your "failures" as learning experiences to help you avoid making mistakes in the future. After you get over the initial shock of diving into a new situation, you'll find it easier to do so later down the road - an automatic solution to your problem.
Speak to your phone psychic if you're interested in further identifying your fears and overcoming them sooner rather than later. A tarot reading can let you know what positives may come from conquering your fear, which may be enough to motivate you to move forward.
