I recently began reflecting on this question… Is there such a thing as a wrong decision?
For most decisions where you need to make a conscious choice – like who you marry, what you major in, whether or not you go to school, what you do for work, etc. I don’t believe there is.
You make decisions that will impact the rest of your life, but I don’t think you do so in a way that will impact you for the worst or the better. Life is full of ups and downs, no matter what choice you would have made. You might not suffer in the same way as a result of your decision, but you will still suffer regardless of what you choose to do… The same thing goes for happiness. Certain aspects of your life may have been better than they are now, but some of them will likely be worse.
Even if you are going through something really bad as “a result of your decision”, you will come out at the end of it all a stronger person than you were.
Anyway, I still have to fight with myself sometimes, because I feel an intense need to control my life, and to always have control over situations that arise in my life. Reality is that outside influences will throw wrenches into your plans regardless of what decision you may choose to make.
So, don’t get so bogged down trying to make the right decision. Just do what you think will be best, and roll with the inevitable punches.
