The sooner we accept that we are willing to deal with failure no matter what happens the easier it will be for you when unexpected and unwanted things happen in your business and in your life.
Try to mitigate risk when doing things by conducting due diligence on whatever to want to get in to. The biggest, first, and best investment you can make is on education about what you want to do and personal development on yourself.
Read books like, The Compound Effect, How to Win Friends and Influence People, 10x, etc... to work on yourself and devour information that specifically pertains to what you are doing.
Stay Focused and have a strong "Why" because when the rah rah motivation wanes and it will your "Why" will give the you discipline and focus to keep going.
I hope this helps anyone who might be having a rough time, second-guessing themselves, hates life, or thought that success was going to happen two weeks after they put up their website.
Stay Focused!!! Have Great Day!!!
