Pass on info about good training events to your friends and contacts. Everyone in business needs training on a regular basis to keep up with trends, to learn new concepts and even for refresher in the basics. But there's a hitch -- many people don't get the training that can help them in their business for a whole raft of reasons: not enough time; didn't know about it; hard to know what's good; don't want to go alone; and so on.
So you be the one who knows about the best training in the area, perhaps for your specific field, but definitely for general business topics (that way you can share the info with more contacts). Have a mechanism, maybe a list on your blog or newsletter, or maybe just jot down good upcoming training events on a 3x5 card and carry it with you.
Even more powerful for you than just telling people about good training, go together. If the experience is a good one, and the stronger the better, a shared positive experience promotes powerful bonding.
Training classes or seminars are also good places to meet new people and broaden your personal sphere, which holds true for the people you attend with as well. Therefore, if you and a few friends do attend training together, balance your attention and time on the people you went with and with the opportunity to meet new people and add new relationships. Make this a conscious effort and be transparent about it, make sure you inform the people you go with and also encourage them, too, to make the most of the training opportunity to meet others.
