With such a large world, naturally the opinions on what success is varies.A lot will say success is when you possess a lot of things. Such as the type of car you drive, the size of your house and the size of your bank account. And yes that is success, because in order for one to possess those things, most of the times, it is due to hard work, dedication, drive and focus.
Dr. Maya Angelou said it best when she said.
Success is liking yourself, liking what you do and liking how you do it.
I believe this quote is saying. Not to be driven so much by possession, but instead seek to be a person of value,. Thus your success is more about who you are, what you are about, your service to others. How you help to make this world a better place.
I believe this quote is saying. YOu/We have to work hard for what it is we want in life, and hard work requires giving up somethings we do not necessarily want to let go of as well as requires doing things you/we feel might be too hard or things we might not ordinary do .And then if I/we do not then we lose out on the things we want and therefore risk unhappiness, fulfillment.
