Some people look at the here and now...what do they have right now or not have right now. However, I am here to tell you that doing such is self deception and destructive. It's similar to how I say that actions always beat words. If the words are true, you will see it in their actions; but, if you do not see the actions the words are all the more malicious. Well, having a good day or a bad day is FICTION, when it comes to determining if something is good or bad. It is more important to look at not only the history of those actions but where they are leading.
Recall the Wizard of Oz. In the story, it was very important that Dorothy stayed on the yellow brick road to get to the castle. Aside from the fact that the entire Wizard of Oz story was written as political satire on the vanity of following a "road" made of GOLD and expecting that to fix everything in their life (spoiler it didn't....it was a false hope given by the one that ran oz), the story does say one thing that is important... where you ARE is not as important as where you are GOING. Where does that road take you or not take you. If you are taking a golden road that is based in a false hope, you will end up as deceived as Dorothy, so it is important to determine if the road that you are on takes you where you want to go.
And, that is the other side to it...where do YOU want to go....YOU...not someone else. There are far too many out there chasing the dreams of of others and making others happy. Then, years down their road, they stop and say, "How the hell did I end up HERE...I don't even LIKE it, here." That is because no one else is responsible for how you respond or where you go, and they know much less than you what it is that you desire. If you don't stand up and speak your desire and say NO, sometimes, you will find yourself in servitude to others happiness and filled with regret of your own.
I have said to my wife, several times, and to others that I don't KNOW where I am going in my life. Indeed, how CAN you know all the steps that are ahead of you. And, knowing all of that would take all the fun out of life. As Jack Sparrow said in Pirates of the Caribbean On Stranger Tides...
"Better to not know which moment may be your last. Every morsel of your entire being alive to the infinite mystery of it all."
Exactly. It is an adventure what lies ahead. However, you CAN and SHOULD take note if the path you are on CAN lead you to happiness or just misery. If you are in a miserable job or relationship, and since people don't change and management doesn't change at the top of companies but rarely, to sit in misery and expect happiness would be fulfilling the definition of insanity to repeat the same process and expect different results. However, if you can look around you and see the POTENTIAL for serendipity (happy surprises or happy accidents as the movie says), well...THAT is LIFE.
So, take an honest stock of where you are and the natural progression of events and make your life decisions based NOT on what you see today but what you expect, tomorrow....and THAT is the key to a happy tomorrow.
