Some people call them filler words, others might know them as crutch words; irrespective of name, these are any sounds, words or entire phrases that does not contribute to the meaning of a sentence.

Whatever field of life you're in and whatever point on the journey you find yourself on, the key is to keep climbing, however slow the progress seems. If you are at the bottom of the rock face and looking up, find someone who will support your desire to climb. As you begin, do not allow the voices of those still at the bottom to persuade you to come back down. They can tell you nothing about a climb they've never made.
With any progress, there is a price to be paid. The question that each must answer for him or herself is this: Am I willing to pay that price?
