The main phrase for this post is "If Only...".
When I say this phrase, one word came to mind, "REGRET(s)". That phrase will only result in one thing, being regretful of what you have done and wishing you could go back in time and change everything. If you knew what would happen in the future, then you would never have the problem of worrying what could happen, the consequences of your actions. Doubting every move you make and hoping that nothing bad or worst situations that could happen may not exist. But it does and you cannot do anything about it. It is done and can never be change or re written. Life moves on and you too. You will keep telling yourself, "If only you did that, If only you did this, If only you knew what you knew now..."
But not knowing is one of the mysteries in life. Sometimes not knowing is better. But there is moment where I second guess everything. If everything was pre-planned, what we did could never be changed, choices that we made is pre-planned and it is not our choice in the first place. It was already known what choice we made and it had play it out by it self as it should. Then isn't it not our fault? We are already planned to do what we did and why do we still suffer for it?
