Today is plenty; right now is enough. Tomorrow will come in good time. Until it does, live the depth of now.
Whats holding you back is the thought that something is holding you back.
The sooner you act, the bigger difference you can make.
Concern yourself more with accepting responsibility than with assigning blame. Let the possibilities inspire you more than the obstacles discourage you.
You cannot expect to get the effect when you neglect to create the cause.
Your level of achievement will rise to meet the level of your purpose.
