Several months ago I heard a business coach give the following advice – "Make your mistakes in a hurry" – the basic premise being that there is time value in our actions much like the time value of money.
Many of our best laid plans fall by the wayside because we stay in the planning and calculating stages way too long. Although I don’t advocate being like Microsoft and releasing operating systems long before they are actually ready for use, I would say that if you have a great idea go ahead and start to implement it. Don’t be afraid of failure. You’ll figure out the 99 wrong ways to do something but you’ll also eventually get to the 1 fantastically efficient way to do it also.
Much the same with learning to sing. If you’re afraid of making a mistake you’ll be so tentative that it’ll take you forever to become accomplished. Make your mistakes fast and confidently 
Try different mental pictures to help your breathing technique until you find something that works for you. Play around with your vocal placement to explore all your resonators to find your best sound or have different match options when singing with other voices. Don’t be afraid to ask for coaching from great singers and when they give you a great tip practice it ruthlessly.
Check out the video for an interesting idea – I’m not sure that I can agree as I think you need time to implement and make permanent your coaching.
