I use to meditate a lot. Now it's like 2-3 times a week. The difference between when im not meditating is of course a lot of reduced stress. I just have a clear sight of everything happening, the solution to problems are always obvious. This is a great feeling and this is why i enjoy and i encourage you to meditate. What to do is simple, there is plenty of meditation you can find on the web. Just find one you like and do it. Do it a lot like for 2 years and master it. Once you master it, it will be natural for you to get this state of mind, this lucidity, even when you are not meditating.
