"It is not what you do once in a while; it’s what you do day in day out that makes the difference"- Jenny Craig
The key factor that makes you a master over a difficult task is a persistent ability to do it on repeated basis. We become perfect at what we repeatedly do.
That is why it is neither an option nor a priority to give up because the little rehearsals you have taken already were meant to prepare you for a success which is very close to you even before you intend to quit.
Do it again and difficult things will lose the power of their difficulties, yielding it up for your victory. Never think you can't, and hence you won't to need practice. Constant repetition is a source of greater accomplishments. Dream big, but start small; bite a tiny part of your heavy tasks each and every day and you will bring them down in no time
Don't postpone your success.
Victory lies ahead of you provided you are prepared to run many short races to reach your long journey!
