My Golden Rule of Networking is simple: Don't keep score.
The bridge between wishing and accomplishing is discipline.
Be like the turtle. If he didn't stick his neck out, he wouldn't get anywhere at all.
Be active, be energetic, be enthusiastic and you will accomplish your object.
Anyone too busy to say thank you will get fewer and fewer chances to say it.
Give your subconscious a chance to work by turning your brain off from time to time. Don't focus on work or solving problems constantly.
