How strong are you?

How strong are you?
I am not asking if you can carry 150 lbs. of weight. What I'm after is your strength of character. How resilient are you to hang on to your dreams amidst the raging forces of discouragement and criticisms?
There are far, too many individuals who never experienced the joy of attaining their desires because other people's influence has significantly (and sometimes negatively) affected their crucial decisions.
Are there instances in your life when other people said that you should not continue your plans because they're never got to work? What did you do? Did you continue your endeavors or did you just follow their command?
If you always adhere to other's beliefs and opinions even though they are contrary to yours, you're just torturing yourself. It is as if you don't have a mind of your own. You are like a shadow following the moves of someone else.
You may listen to other people's advices, but never let them control you. If their advices would contribute to your success and well being, then follow them. However, if they would hinder you and stray you away from what you really want in life, then you have to make a stand and pursue your heart's aspirations.
Sure there would be criticisms. However, if you always avoid them, then you will never be truly happy.
As one famous person said, "There is a sure way to avoid criticisms, be nothing and do nothing. This remedy never fails." True enough.
