Life is meant to give us experiences some good , some bad from which we learn essential life lessons. These experiences guide us in our future. Experiences teach us what to accept and what to decline. Changes are part of our life . If we don’t change with time , time will change us. Our past makes our future . Past should only be remembered for the experiences and not for hurt , rejection , failure etc. These have to be forgotten and forgiven if we want to make progress in life. You have to focus all your energy on the present as per your life goals. Thinking about sad events of the past doesn’t get you anywhere and hinders your personal development. Have your goals , have focused mind and get on with your life visualizing new paths for you towards abundant life. If you want to bring about lasting changes in your life , don’t fight the old past events and focus all of your energy on building the new. ~ Socrates
The best way to love someone is not to change them 
You can’t change what’s going on around you 
People will notice the change in your attitude 
No matter how much it hurts now
