In the end I believe that limits exist and are made to emphasize that we are human beings those full of limitations and limits exist to keep everything in balance. Have you ever imagined if our body continues to grow tall without limit? How troublesome is that? Likewise if the desires and passions in our humanity grow without limits.
Now if I look back, walking through memory lane, I can't stop being grateful that my daughter and me both are doing well and supporting each other and we are contented. I count myself as contented instead of successful. I am entrusted a good job, with its privilege, and level of influence that enables me to serve people and share good things. I am more than happy when knowing that my existence brings good influence to others.
I don't think that I have to be successful according to anyone's or any standards. I do the best in my ability to succeed, not only to my satisfaction but to be able to bless others. For me a meaningful life is more noble than just being successful and happy.
The world of reality has its limit, the world of imagination is boundless. (Jean-Jacques Rousseau)
