There are 3 things that are obvious, they are eternal, they are infinite, and they are at the core of what it means to live in joy. And the first is you are not alone. The second is you have a purpose. The third is, if you can combine not being alone, namely the voice of G-d, the direction of G-d, which can be ascertained (see my book Kabbalah-Love) then you can understand the purpose.
