I use meditation daily and actively practice Buddhism. The things I love about it is, it's not meant to be about belief, but about behavior - try it and see if it works for you - like DB.
One of the fundamental principals is that suffering is caused by trying to seek satisfaction in things that are inherently impermanent - we cannot control this.
So relationships, actions, promises, life, finances, plans, expectations, etc - all of these things are our downfall when we grow attached to them and we grow disappointed or suffer when they fall apart, which they always do in one way shape or form because they are all not permanent.
These are things I try to remember and focus as I meditate. It normally does help and calm, but as always, it's tough to have your brain/logic be on the same page as your heart/emotions.
