If you want to succeed in business you can never quit. There are countless examples of successful people who routinely faced major obstacles along their path to greatness. They did not roll over and play dead. They did not quit. Successful people are tenacious.
I once heard it said that the average sales person gives up on a prospect after five unanswered calls, but that the average business person does not call back until they receive seven phone calls from a potential vendor. That means that the tenacious sales person will get more appointments (and sales) than the average sales professional.
Business networking can be very complicated. Many people think networking is just going to "after-hours" events, drinking some beers and waiting for the referrals to role in. This is why so many people give up on networking. When they do not see immediate results they trash the whole concept.
To see real results with your networking means that you have to be tenacious. Many people you meet can be great connections for you, however it takes a long time to build meaningful relationships. Stick with it. You cannot reach the top by quitting half way up the mountain!
Visualize your goal and then go for it. Do not let anyone or anything stand in your way. Avoid the nay-sayers. Be tenacious. Grasp victory!!!
Have A Great Day.
