We're not required to know all the answers. We're especially not required to know all the answers when we aren't even sure what questions we are trying to sort out. The only requirement when it comes to our life's questions is that we let ourselves ask them, so we can experience ourselves fully as beings wholly involved in our lives.
There may be no satisfying answers to our questions.
The response we're given may not give us immediate gratification. Receiving no answer or a not-immediately-gratifying answer to our questions can be its own kind of answer: a wait, or a no, that represents a direction change rather than a dead end.
From the meaning of life to what eating utensil to use, if we can't figure it out, we can ask quite simply and directly, as we can ask any question. We get to interact with our fellow human-beings, and we get to give someone the gratification of feeling helpful, superior, or more knowledgeable.
Won't my ego bruise from asking questions revealing that I don't know something?
Only if it's over-inflated.
When our egos are over-inflated, we're forever bruised and battered, forever bumping into other over-inflated, bruised and battered egos, forever getting hurt and hurting others.
Without asking (and letting ourselves appear vulnerable) we can't find true direction. Until we follow our inner need for direction into greater fulfilment and harmony, we strangle our very source of living fully.
