To surround yourself with an inspiration network you can find people at your job that are positive. If you do not sit with them at lunchtime, change that. Ask them if you can join them. Strike up conversations throughout the day with the positive people at work. Before you know it, you will become one of their closest co-working friends. Some co-workers meet after hours and do dinners together.
It would be a fantastic evening out with people that are very positive. If you currently hang around negative co-workers and go out to dinner surely they constantly talk badly about other co-workers and their spouse or significant other. You do not need this negativity in your life-ever. If you continue to hang around people that are so negative, you too, will become one of them. Negativity spreads just as easily as positivity does.
