We are all familiar with the famous Newton's third law of motion which states that for every action, there is an equal and opposite reaction. Let's try to apply this to our daily lives.
For Every Action There Is A Resulting Consequence (Reaction)
Every action we make in life has a resulting consequence to us or to those around us. It might not be as immediate as the physic term, but it would later manifest in the nearest future.
I've always been someone who doesn't believe in luck. There really is nothing like good luck and bad luck, it's just the resulting reaction from our actions. Some actions might yield bad reactions even if that wasn't what was intended, (something people often term as bad luck) but that doesn't mean it wasn't as a result of your actions.
Nobody likes bad results, everyone wishes to be successful in everything that they do but the problem with this is how do you manage your actions to result into good reactions. Sometimes it seems to you that you are making the best decisions and then all of a sudden the result seems to be far fetched from what you anticipated. It's not bad luck, you just didn't get something right. Most times this is caused by ignorance. Ever noticed that you become better at things the more you do them? That's because with each trial, you acquire some new knowledge which you were ignorant of at the early stage and now you have altered your actions with the new knowledge you have gained on repeated trial and you now have better results.
Conclusion
In all that we do, let's try to analyse our actions and all the probable reactions that will result so as to avoid thoughts of had I known. We alone are the craft men and writers of our future, take actions that will lead to a better reaction for you in the future.
