This idealism may be due to a tendency within us to be perfectionalists, but sometimes always thinking that it's not the right time now, I'll start it when I have it all, can be all that holds us back from actually carrying out the task/ initiative. Having done say 80-90% of something is generally always better than have done nothing at all...
So even though today may not seem like the ideal day/ time to start, tomorrow may not be either! And every step counts, so why not start your journey with that one first step today :)
