Being happy is of the utmost importance.
Success in anything is through happiness. More support of Nature comes from being happy.
Under all circumstances be happy, even if you have to force it a bit to change some long-standing habits.
Just think of any negativity that comes to you as rain - drop falling into the ocean of your bliss.
You may not always have an ocean of bliss, but think that way anyway and it will help it come.
Doubting is not blissful and does not create happiness.
Be happy, healthy and let all that love flow through your heart.
