When you surrender and stop resisting and stop trying to change that which you can't change, but be in the moment, be fully open to the blessings you've already received and those that are yet to come and stand in that space of gratitude ... and look at where you are and how far you've come and what you've accomplished - when you can claim THAT and SEE that, the literal vibration of your life will change.

Live life and take chances. Believe that everything happens for a reason and don't regret. Love to the fullest and you will find true happiness in life. Realize that things go wrong and people change, but things do go on. Sometimes things weren't meant to be. What is supposed to happen will work its way out.
