Why do we always end up saying,"I wish life had a rewind button."?
We make stupid mistakes and then later regret on it. We always think -
a) If I would've apologized to him/her, I wouldn't be having this day today.
b) What if I had chose another carrier instead of what shitty work I am doing right now?
c) I wish I had took proper care of my body in the mean time I had.
d) I wish I asked out him/her at that time rather regretting about it today.
We can still make our lives more happy and grateful if we don't show fears and do something which we do not then regret later in life because fears are temporary but regrets stay forever. if we have the courage to do something which we do not want to regret later we would be living a way more productive and happy life.
The worst feeling is regretting not have done something when you had the chance. If you have any regrets and if you have the time to correct it then just go for it and if you don't then just look up and move on in your life because the decision you took at that time made you the person who you are today.
