Don't count on luck for your success. Set your sights on hard work and dedication. Focus on working hard and being dedicated to what you do and you will feel lucky that you have done so.
As humans tend to avoid change, saying "Well we've always done this." So when doing something isn't working then it must be time to make a change. Have the courage to make a change. You can do it.
We often forget it's okay to say no and you can do it without being rude. Sometimes saying no is in your best interest.
