How are your thoughts holding you back? Are you thinking positively or negatively? This goes down to your roots and it is time to let go. It is literally as simple as changing the way that you think. If you think you can do something you can do it. Stop worrying about the end result. There is no harm in trying. You won’t know until you try.
What is something you have been holding back from? Something you have been avoiding or wanting to do? Listen to your inner voice. This is a time for self-discovery. You might as well jump.
