Probably one of the most important rules of thumb, is if you want something badly enough you will follow up. Not every two days, but set a timeline between you and your client when to follow up and make sure you keep to this.
Sometimes, life and work gets in the way of making this follow up effective or when originally timed, but more often than not, being the human beings we are, often procrastination can get in the way. And you nor I are not the first people in the world to suffer from this affliction. The only way we can change this is doing it.
So if you feel that you have put off that follow-up call, email or meeting for too long, what's the worst that could happen? The client could say no, give the business to a competitor or might just have been as caught up as you and was happily reminded by you about your original call and happy to continue. You could even be the bearer of a greater surprise, the business!
Travel well peeps!
