While you may find progress difficult today, it is important that you stay focussed.
Success and growth are not the same thing, but they are related. Success means that you have achieved part or all of your goal, and that is great. However, growth is what really matters. Growth is what we are really aiming for because it sharpens our tools and leads us towards success.
Don't make promises that you can't keep. It will only weaken your credibility.
