You are very right. But it is also very contradictory, because when we have so many things to do it is difficult to know which one to start with or give it the proper priority, of course for one of them we must start. And once you do it you just have to finish with that one so that you do not get overwhelmed with the other things you have to do.
All the time you can not take advantage of all the opportunities and fall into the loop, by which we get hold of those multiple opportunities, simply that era, and you will depend on the achievement or failure of it, you just have to put in the right effort to finish what that is started
