You don't have to work at being in the high vibration that is natural to you, because it is natural to you.
But you do have to stop holding the thoughts that cause you to lower your vibration.
It's a matter of no longer giving your attention to things that don't allow your cork to float or don't allow you to vibrate in harmony with who you really are.
Did you see that? Your natural state is high.... it is negativity that lowers it. You are inherently high, vibrationally speaking. This is the best news ever!
You don't have to work at it, you already have it in you. This is all the more reason to eliminate negativity from your life. Negative people and/or situations keep you from your natural emotions of joy and happiness.
You know all the people you think you can fix by showing them the way? If they could only see how happy you are. Or if they would only take the time to notice how you 'fill them up' with attention, concern and love. They will surely follow your example, will they not? Probably not, they will be who they are.
That is their job, it's everyone's job, to be who they are. By trying to fix others, you are just avoiding looking at your own stuff. Use your energy for fixing yourself, rid yourself of negative forces and actually, truly be happy. Only then will you vibrate in harmony with who you really are.
