The effort required to succeed and to fail is the same.
You will wake up.
You will work.
You will spend money and time on necessities and something else.
The difference is where you put your spare money and spare time.
If you don"t like the results you are getting, you can look at how you are spending your spare resources. Try something else.
If you have a kid, when do you quit trying to teach him or her how to walk? Until he or she walks right? You don"t quit and say I"ve used too much resources.
Never lose heart. Failure is directly related to the strategy used or the skill level of your execution.
