I really like DBT or dialectical behavioral therapy. It helps me concentrate on the present moment and be able to do one thing at a time. So far I'm not very good at it but it takes practice. The teachers I go to are very good. It doesn't help with everything, or at least not yet, but it is a good tool. It all starts with practice and willingness to try it, even if it sounds a little weird sometimes. The meditation is the hardest part for me.
