There is a time and place to concentrate on each. Learn what those times are and act on them. High performance comes from a full tank. Make sure you get enough Rest, Recovery and Re-Creation to be at your best a high percentage of the time. Look for ideas you can use, outside the field of swimming.
Creativity comes from a full subconscious.
Remember, friends come and go, but enemies accumulate. Be action oriented. No endless cycles of study and debate. Place the needs of your family over the demands of your work. Take your responsibilities seriously, but don't take yourself too seriously.
