Just a couple things to think about before you make a decision.
If you choose to practice two arts at once make sure the philosophies are not contradictory to one another. (This will mess with your head something terrible
) Also as others have stated earlier keep the two arts separate in your mind and in physical training. Remember they are not the same. In addition, this is my personal opinion you should choose one art to start with and make sure you really have a solid knowledge of both physical technique and philosophy. That way when you choose a second art to study you know exactly what you want and don't want. Thought I'd share some things I've learned along the way. Do as you like
