Focus on the solution, not the problem.

We can all find "reasons" why we cannot succeed.  Instead of focussing on the can'ts start to concentrate on the cans. 

I cannot write good emails...  I can get someone to help me write good emails

I cannot talk to people.....  I can overcome it or get someone like my upline to help me

I cannot explain things well......  I can study the program I am in until I understand it  but in the meantime use the tools and people that have been available to me.

I cannot do this.....  Well if you really believe that then you are probably right.

You must be willing to help yourself, so stay focused, stay positive, and do not be afraid to ask for help.  When you do ask for help keep an open mind because it might not be what you wanted to hear.
